1255563 玖、發明說明： 【發明所屬之技術領域】 本發明係關於光學模組片及其製造方法，尤其是關於將 電性連接於球狀元件的導電線及固定導電線用的絕緣性的 張力線材編織成網眼狀的光學核組片。 【先前技術】 現時，普通已實用化的太陽電池，係利用將雜質擴散於 平面狀的半導體晶圓上等而形成平面狀的pn接面。如此般 構成的太陽電池，在垂直將光入射於受光面的情況其輸出 成為最大，但是其輸出也隨著光的入射角對受光面的傾斜 而降低。藉此，如此般構成的太陽電池的指向特性強，因 此難謂可經常有效利用光，另外，因為是將半導體結晶的 晶錠切片而形成晶圓，因此藉由切割等的加工損失大，此 也連帶關係到製造成本的增加。 由於上述緣故，美國專利4 5 8 1 1 0 3號中揭示有將高純度 金屬矽原料熔化並使其滴下，用以製造粒狀的p型結晶， 於該p型結晶上擴散η型的雜質，形成球面狀的pn接面的 太陽電池元件及藉由鋁箔連接該太陽電池元件的太陽電池 模組。該太陽電池模組不是從將該球狀的太陽電池元件模 組化前形成已獨立的電極，而是在形成於1片鋁箔的孔内 機械式地壓入太陽電池元件以便與η型表面電性連接，然 後即由蝕刻處理等除去從孔向下方突出的太陽電池元件的 η型層的表面一部分，以使作為芯的ρ型矽曝露，使該ρ 型矽與其他的鋁箔表面接觸而形成正電極。利用具有多數 6 326\總檔\92\92130630\92130630(替換)-1 進行該連接，藉由2片鋁箔進行 形成及太陽電池元件間的並聯連 般構成太陽電池模組時’具有藉 電極的形成及並聯連接的特長， 鋁箔後使Ρ型區域曝露，因此要 特性及良好與否有其困難。另 為限定於並聯連接，因此為提升 太陽電池模組結線。若太陽電池 铭箔間的間隔變短，要將鋁箔彼 成製造步驟的複雜化。因為正負 池元件的中心的下方、亦即兩電 因此流動於正負兩電極間的電流 不僅有無法充分提高光電變換效 羯遮光’並將受光面限定在較I呂 全方向的光，以致無法提高輸出 9 - 1 6 2 4 3 4號公報揭示有藉由編 線材；及橫向延伸的玻璃纖維而 複數球狀的太陽電池元件的薄片 池中係利用導體線材來支持太陽 體線材間的絕緣。 -1 6 2 4 3 4號公報所記載的太陽電 在連接η型層與負極導體線材後 ρ型區域曝露，連接正極導體線 7 1255563 pn接面的太陽電池元件來 複數太陽電池元件的電極 接以達成模組化。若如此 由2片鋁箔同時進行接合 但是因為在連接η型層與 判斷每個太陽電池元件的 外，若如此般構成時，因 輸出電壓必須要與其他的 元件的直徑小的話，2片 此絕緣變得困難，從而造 電極的位置處於較太陽電 極形成於非對稱的位置， 偏向電極距離短的處所， 率等的缺點，此外藉由鋁 箔的上方，而有無法受取 的缺點。 曰本專利公報之特開平 織入縱向延伸的線狀導體 形成的玻璃纖維布以支持 狀的太陽電池。該太陽電 電池元件，以簡單進行導 但是，在上述特開平9 池所設的電池元件中，也 使全周由η型層所覆被的 326\總檔\92\92130630\92130630(替換)-1 1255563 材與P型區域。在連接導體線材與太陽電池元件之前，因 為僅η型層曝露於外部，因此在連接前無法檢查每一個太 陽電池元件，而產生與上述引用文獻相同的問題。另外， 與ρ型區域連接的正極導體線材也連接於η型層，因此利 用不斷照射光以進行電性化學蝕刻處理，以進行ρη接面隔 離，使正極導體線材僅連接於ρ型區域，但在各太陽電池 元件中因為蝕刻處理的進行速度各異，因此要確實在所有 的太陽電池元件進行ρη接面隔離有其困難。 在該公報之太陽電池元件中，也因為在相對中心的非對 稱位置連接正極導體和負極導體，因此也產生與上述引用 文獻相同的問題。更且，該問題在將太陽電池元件換為球 狀的發光二極體時，也只在導體線材間的狹窄區域發光， 因此無法使光向著全部方向出射，從而有失去球狀的發光 二極體的優點的問題。 在此，如國際公開公報W 0 9 8 / 1 5 9 8 3號公報所示，本案 申請人提出屬太陽電池元件或發光元件的複數球狀元件及 連接該球狀元件的光學模組片。該球狀元件具備：球狀的 ρ型（或η型）的單結晶半導體（矽等）；形成於該單結晶半 導體的表面附近的η型（或ρ型）的擴散層；及大致球面狀 的ρη接面；設置於挾持球狀單結晶半導體的中心的對向位 置的一對正負電極。將此等多數之球狀元件配設為複數行 複數列的矩陣狀，利用串聯或並聯連接此等，來構成光學 模組片。 因為在此等球狀元件，在挾持其中心的對向位置設有電 3 2 6\總檔\92\9213 063 0\9213063 0(替換)-1 8 1255563 極，因此利用以直接接觸鄰接之球狀元件的正電極及負電 極的方式進行排列，便可簡單串聯連接複數之球狀元件， 但是並聯連接各球狀元件則並不容易。 為了改善該問題，本案申請人在國際公開公報 W 0 0 3 / 0 1 7 3 8 2號公報中，藉由平行配設的2根導電線，以 夾入使電極的方向一致而配設的球狀元件的正負電極的方 式並聯連接而形成球狀元件列，更且，利用連接鄰接之球 狀元件列的導電線，串聯連接球狀元件列。 但是，在該光學模組片中，有導電線的長度方向的拉伸 強度強，而在垂直方向卻非常弱的問題，有使連接球狀元 件與導電線的連接簡單，以提高生產效率的必要。 本發明之目的在於，提供一種可僅由合格的球狀元件構 成的光學模組片；提供一種拉伸強度強的光學模組片；提 供一種球狀元件的光電變換或電光變換的效率高的光學模 組片；提供一種製造容易的光學模組片。本發明之其他目 的，從本發明之效果的記載及實施形態的記載便可知曉。 【發明内容】 本發明之光學模組片，包括：複數球狀元件，係具有受 光或發光功能的複數球狀元件，各個具有大致呈球面狀的 pn接面、與分別連接於pn接面的兩極而位於球狀元件的 兩端的正負導電線連接部，且使極性一致而配置為矩陣 狀；平行配置的複數導電線，係針對複數行的各個球狀元 件，介由各行的複數球狀元件的正負導電線連接部，電性 並聯連接各行的複數球狀元件；及絕緣性的複數張力線 326\總檔\92\92130630\92]30630(替換)-1 9 1255563 材，係與複數導電線呈垂直狀配置於球狀元件的列與列之 間，為固定複數導電線而與複數導電線編織為網眼狀。 在為該受光模組片的情況，與光的入射方向無關，使光 入射於受光模組片，當該光極性一致照射於配置為矩陣狀 的複數球狀元件時，由形成於球狀元件的大致球面狀的pn 接面接受光，藉由球狀元件的受光功能變換為電能。該電 能介由連接於ρ η接面的兩極而位於球狀元件的兩端的正 負導電線連接部輸出於外部。在為發光模組片的情況，從 導電線介由導電線連接部供應給球狀元件的電能，藉由球 狀元件的pn接面變換為光能，並將該光出射於外部。 因為球狀元件具有連接於pn接面的兩極的正負導電線 連接部，因此，在將球狀元件組入光學模組片前可檢查球 狀元件，其結果可僅將合格的球狀元件組入光學模組片， 可穩定製造高品質者。另外，利用組入前而於球狀元件形 成正負導電線連接部，導電線連接部與導電線的連接變得 簡單，製造步驟亦變得簡單。 因為延伸於行方向的複數導電線及延伸於列方向的複 數絕緣性的張力線材編織為網眼狀，因此強度優良。因為 球狀元件的正負導電線連接部，係連接於大致球面狀的pn 接面且處於球狀元件的兩端，因此可有效應用pn接面的全 域，可提高電力及光的產生效率。 在此，除以上之構成外，可適宜採用如下的構成。 (1 )在上述各球狀元件，上述正負導電線連接部係位於 挾持球狀元件的中心的對向狀的位置。 10 326\總檔\92\92130630\92130630(替換)-1 1255563 (2 )設置透明合成樹脂或透明玻璃製的密封構件，其將 上述複數球狀元件收容為和複數導電線及複數張力線材共 同埋入的狀態。 (3 )上述各球狀元件係為光電二極體元件或太陽電池元 件。 (4 )上述各球狀元件係為發光二極體元件。 (5 )上述導電線係為使用從焊錫、導電性合成樹脂與合 金化金屬中所選擇的任一者，來連接正負導電線連接部者。 (6 )以上述導電線材的至少一部分曝露的方式，埋入密 封構件。 (7 )在上述球狀元件的行與行之間具備有與導電線平行 編織於導電線的絕緣性的張力線材。 (8 )上述密封構件係使用透明合成樹脂材料而構成的撓 性構件。 (9 )在與上述密封構件的光的入射側相反側的面，構成 反射從入射側入射的光的反射膜。 (1 0 )上述密封構件係由將複數球狀元件收容為埋入狀 態的具柔軟性的透明的緩衝層；及接合於該緩衝層的兩面 的透明的表面層所構成。 (1 1 )上述密封構件具有由高分子材料所構成的熱反射 膜，該高分子材料選擇性反射藉由球狀元件而無法吸收的 熱線。 (1 2 )具有複數行串聯連接著並列上述複數球狀元件的 導電線的串聯連接機構。 11 326\總檔\92\92130630\92130630(替換)-1 1255563 本發明之光學模組片之製造方法，係在具備：複數球狀 元件，係配設為矩陣狀的具有受光或發光功能的複數球狀 元件；導電線，電性並聯連接各行的複數球狀元件；及絕 緣性的張力線材，為固定導電線而與導電線編織為網眼狀 的光學模組片之製造方法中，具備如下的步驟：製造具有 正負導電線連接部的球狀元件的球狀元件製造步驟；及藉 由依流動於導電線的電流的焦耳熱熔化連接球狀元件與導 電線用的接合構件，而由接合構件連接球狀元件與導電線 的連接步驟。 根據該光學模組片之製造方法，首先，在球狀元件製造 步驟，製造具有正負導電線連接部的複數球狀元件，其次， 在連接步驟中，藉由依流動於導電線的電流所溶化的接合 構件，並聯連接配列為矩陣狀的各行的複數球狀元件與導 電線。 藉此，介由該導電線連接部可檢查球狀元件為良品或不 良品，可防止不良品之球狀元件組入光學模組片。另外， 利用組入前而於球狀元件形成正負導電線連接部，導電線 連接部與導電線的連接變得確實而簡單，製造步驟亦變得 簡單。另外，因為藉由依流動於導電線的電流熔化接合構 件，以連接導電線與球狀元件，因此，可熱效率良好且容 易連接，省能源化及製造步驟變得簡單。 【實施方式】 以下，說明本發明之最佳實施形態。 本實施形態係為將本發明應用於呈複數行複數列的矩 12 326\總檔\92\92130630\92130630(替換)-1 1255563 陣狀配設球狀的太陽電池元件的受光模組片（太陽電池模 組片）的情況的一例。 如圖1、圖2所示，該受光模組片1具有多數的太陽電 池元件2 (相當於球狀元件）、網眼狀構件3 (導電線混織玻 璃編織物）及密封構件4等。 因為在本案申請人申請之國際公開公報W 0 9 8 / 1 5 9 8 3號 及W 0 0 3 / 0 3 6 7 3 1號等揭示有與太陽電池元件2大致相同構 成的太陽電池元件，故在此僅做簡單說明。 如圖1、圖2所示，多數的太陽電池元件2具有將光能 轉換為電能的受光功能，並使極性一致而配置為矩陣狀。 例如，每一瓦特的發電輸出使用約2 0 0 0個太陽電池元件2。 如圖3所示，各太陽電池元件2係將電阻率為0. 3〜1 Ω m 程度的P型單結晶矽組成的直徑約為0 . 6〜2 . 0 m m的球狀結 晶1 0作為素材而形成。在該球狀結晶1 0的一端部形成有 平坦面1 1。在除平坦面1 1以外的球狀結晶1 0表面部的大 致全區域，形成全區域擴散有磷（P )的η +型擴散層1 2 (厚度 約為0 . 4〜0 . 5 // m )，在該η +型擴散層1 2與ρ型區域的境界 面形成有大致球面狀的ρ η接面1 3。在球狀結晶1 0的直徑 約為1 . 0 m m的情況，平坦面1 1的直徑約形成為0 . 5 m m。但 是，平坦面11的直徑也可為0.5mm以下。 在平坦面1 1設有正電極1 4 (相當於導電線連接部），在 挾持球狀結晶1 0的中心且與正電極1 4對向的位置設有負 電極1 5 (相當於導電線連接部）。正電極1 4係連接於球狀 結晶1 0的ρ型區域，負電極1 5係連接於η+型擴散層1 2。 326\總檔\92\92130630\92130630(替換)-1 13 1255563 正電極1 4係燒結鋁膠而形成，負電極1 5係燒結銀膠而形 成。在除正電極1 4與負電極1 5以外的全表面，形成有 S i〇2 (或T i 0 2)的絕緣膜組成的反射防止膜1 6 (厚度約為 0 . 6〜0 . 7 // m )。該太陽電池元件2具有受光功能，其接受太 陽光而於電極1 4、1 5之間產生0 . 5〜0 . 6 V的光起電力。 如圖2、圖4及圖5所示，網眼狀構件3具有正極用導 電線2 0、負極用導電線2 1及玻璃纖維製的張力線材2 2。 導電線2 0、2 1係為由鎳（4 2 % )、鐵（5 2 % )及鉻（6 % )的合金組 成的直徑為120/zm的線材，其表面形成有鍵錫層（厚度2〜3 // m ) 〇 如圖2所示，兩導電線2 0、2 1均平行延伸於行方向， 其鄰接之太陽電池元件2的各行的正極用導電線2 0與負極 用導電線2 1的中心線的間隔約為0 . 7 5 m in ^各行的太陽電 池元件2與鄰接行的太陽電池元件2的中心的間隔約為 1.75mm。正極用導電線2 0係介由錫膠2 3而電性連接於正 電極1 4，負極用導電線21係介由錫膠2 3而電性連接於負 電極1 5。各行複數的太陽電池元件2係藉由兩導電線2 0 ' 2 1電性並聯連接，同時，全部行的太陽電池元件2係電性 串聯連接。但是，關於此將於其後詳述。 又，導電線並不限於上述構成者，也可為鐵、鐵（58%)· 鎳（4 2 % )合金線、其他的鐵合金線、銅線、鈹銅線、磷青銅 線、其他的銅合金線、銀、銀合金線、鎳、鎳合金線等構 成，也可為由此等的材料製成的細線所搓成的搓線所構 成，可考慮應用電性、機械、化學的性質等。在此等中， 14 326\總檔\92\92130630\92130630(替換)-1 1255563 尤其是鈹銅線或磷青銅線的線材具有彈力，因此可確實保 持與太陽電池元件2的接觸。 張力線材2 2係以與導電線2 0、2 1垂直的方式沿著列方 向延伸而配置於各列的太陽電池元件2與鄰接列之太陽電 池元件2之間。各張力線材2 2係藉由搓製7根玻璃纖維（直 徑約為9 . 0 // m )而形成，將此等3根張力線材2 2作為一 組，以間距約1 . 7 5 m m的間隔配置於各列間。為固定導電線 2 0、2 1，各張力線材2 2係以上下縫製的方式編織入兩導電 線2 0、2 1之間，將複數的導電線2 0、21與複數的張力線 材2 2編織為網眼狀，而形成網眼狀構件3。 如圖6所示，密封構件4係為保護多數的太陽電池元件 2與網眼狀構件3的目的5而形成為將多數的太1%電池元 件2、導電線2 0、2 1與張力線材2 2收容為埋入狀態。該 密封構件4係使用絕緣性的透明聚對二曱苯樹脂形成厚度 約1 0 0 // m的薄片狀。該聚對二曱苯樹脂具有如下的特長： 即、可進行在微細部分處針孔存在少的均勻塗敷的、氣體 或水蒸氣的透過性少、對放射線的穩定度高、折射率（約為 1 . 6 1 )高、且對太陽電池元件2的表面的反射損失少等的特 長。藉此，該密封構件4可形成為薄薄地覆被於太陽電池 元件2的表面的狀態，因此，具有受光的指向性寬廣、反 射損失少，且因其彎曲性而輕量、拉伸或彎曲強度增高、 集採光效率高等的優點。 根據該受光模組片1，與光的入射方向無關，使光入射 於受光模組片1，當該光極性一致照射於配置為矩陣狀的 326\總檔\92\92130630\92130630(替換)-1 15 1255563 複數球狀元件2時，由形成於太陽電池元件2的大致球面 狀的pn接面1 3接受光，藉由太陽電池元件2的受光功能 變換為電能。該電能介由連接於ρ η接面1 3的兩極而挾持 太陽電池元件2的中心的對向的正負電極1 4、1 5輸出於外 部。 接著，圖7顯示含於受光模組片1内的太陽電池模組的 等效電路3 0。該等效電路3 0例如係為將排列為複數行複 數列的矩陣狀的多數太陽電池元件2的各個變換為二極體 3 1。如該等效電路3 0所不1各行的二極體3 1 (太陽電池元 件2 )係藉由正極用導電線2 0及負極用導電線2 1所並聯連 接，更且，各行的正極用導電線2 0係藉由串聯用導電線 3 4串聯連接於鄰接行的負極用導電線2卜若令1個太陽電 池元件2的輸出為0. 6 V，列數為m且行數為η，則在正極 端子3 2與負極端子3 3之間產生約η X 0 . 6 V的光起電力。 若令在1個太陽電池元件2產生的電流為I，則從正極端 子3 2向外部負荷輸出m X I的電流。 如此般，利用一個個串並聯連接多數太陽電池元件2， 即使光未入射於受光模組片1的一部分，一部分的太陽電 池元件2為發電不可能的狀態，因為經由其他的太陽電池 元件2流動電流，因此可將輸出減少的影響控制在最小限。 再者，說明以上說明的受光模組片的製造方法。 最初，參照圖8說明本發明之太陽電池元件2的製造方 法，但關於該製造方法，因為在本案申請人申請之國際公 報W 0 9 8 / 1 5 9 8 3號及W 0 0 3 / 0 3 6 7 3 1號有詳細說明，故在此僅 16 326\總檔\92\92130630\92130630(替換)-1 1255563 做簡單說明。 首先，將熔化狀態的碎的液滴按各定量自由落下，在其 途中藉由過冷卻的急速凝固形成直徑約1 . 0 m m的p型球狀 單結晶1 0，機械式研磨該球狀單結晶1 0的一部分形成平 坦面1 1 (參照圖8 ( a ))。 其次，在包含約1 0 0 0 °C的水蒸氣的氧氣中加熱球狀單結 晶1 0約4 0分鐘，形成厚度約0 . 3 μ m的氧化矽膜3 5 (參照 圖8 ( b ))。接著，為僅在所需的區域將氧化矽膜3 5作為熱 擴散雜質（η型雜質）的罩幕，在玻璃板上將耐酸性的石臘 熔化成均勻的厚度，將平坦面1 1抵壓於該石臘的表面，使 石臘固化。接著，浸潰於緩蝕刻液（Ν Η 4 H F 2水溶液）内，僅 蝕刻除去從固化的石臘曝露的氧化矽膜3 5，其後，從玻璃 板上取下球狀單結晶1 0，除去石臘（參照圖8 ( c ))。 再者，在使氧三氯化磷（Ρ 0 C 13)液氣化的氮運載氣體中以 約9 6 0 °C加熱球狀單結晶1 0約3分鐘，在未形成氧化矽膜 3 5的球狀單結晶1 0的表面形成磷矽酸鹽玻璃膜3 6，更且， 轉換為將環境氣體乾燥的氧氣加熱約9 8 (TC 、6 0秒鐘，將 η型雜質（磷）熱擴散於球狀單結晶1 0的表面附近的内部。 如此般擴散η型雜質，將η+型擴散層1 2形成於由屬罩幕 的氧化矽膜3 5所覆被的平坦面1 1及其附近以外的部位， 同時，在該η+型擴散層1 2與球狀單結晶1 0的ρ型區域的 境界面形成ρ η接面1 3 (參照圖8 ( d ))。 再者，由緩蝕刻液除去平坦面1 1及其附近以外的氧化 矽膜3 5，再度，在乾燥氧氣中加熱約8 0 0 °C、6 0秒鐘，在 17 326\總檔、\92\92130630\92130630(替換)-1 1255563 球狀單結晶1 〇的全表面形成氧化矽膜組成的也屬鈍化膜 的反射防止膜1 6 (參照圖8 ( e ))。 再者，為形成正電極1 4而於平坦面1 1點式印刷鋁膠 3 7，為形成負電極1 5而於挾持球狀單結晶1 0的中心且與 平坦面1 1對向的部位的η+型擴散層1 2的表面點式印刷銀 膠3 8，在氮氣中以約8 0 (TC加熱處理該狀態的球狀單結晶 1 0約6 0分鐘，鋁膠3 7及銀膠3 8貫穿反射防止膜1 6，並 使铭膠3 7與球狀早結晶1 0的ρ型區域5銀膠3 8與η型 擴散層1 2分別低電阻接觸（歐姆接觸），完成太陽電池元件 2 (參照圖3 )。 再者，藉由太陽模擬光源的光照射下測定完成之太陽電 子元件2的電壓-電流特性，以便將太陽電池元件2選為良 品與不良品。 再者，如圖9所示，為位置定位太陽電池元件2，準備 以指定間隔形成定位孔4 0的石英製定位夾具4 1。接著， 使電極1 4、1 5的方向（電極1 4、1 5的極性）一致將判定為 合格的太陽電池元件2配設於定位夾具4 1的定位孔4 0。 又，因為在太陽電池元件2形成有平坦面11，因此可容易 辨識正負的電極1 4、1 5，可簡單地將電極1 4、1 5的方向 配設為一致。 配設於定位夾具4 1的太陽電池元件2的水平面上的赤 道線，與定位夾具41的上面大致相同高度。接著，為防止 太陽電池元件2的移動或旋轉，使定位孔4 0内減壓而將太 陽電池元件2固定於定位孔4 0。又，在定位夾具41的上 18 326\總檔\92\92130630\92130630(替換)-1 1255563 面塗敷碳或氮化硼膜，以便不致與錫膠2 3等的接合材接 合。 接著，準備編織入導電線2 0、21與張力線材2 2的網眼 狀構件3，藉由點式印刷或分配器的吐出以使錫膠2 3覆被 於網眼狀構件3的正極用導電線2 0與連接著正電極1 4的 部位、負極用導電線21與連接著負電極1 5的部位，從上 方將該網眼狀構件3覆被於固定於定位夾具4 1上的太陽電 池元件2上。接著，藉由抵壓夾具（省略圖示）使網眼狀構 件3與定位夾具41的上面密接，同時，使覆被於導電線 2 0、21的錫膠2 3與電極1 4、1 5密接。接著，以在定位夾 具4 1載置多數的太陽電池元件2與網眼狀構件3的狀態， 對於錫膠2 3照射依紅外線燈的聚光束以熔化錫膠2 3，藉 由錫膠2 3電性連接導電線2 0與電極1 4，電性連接導電線 2 1與電極1 5。再者，洗淨除去含於錫膠2 3内的助焊劑並 予以乾燥。 又，作為其他的連接方法，也可於導電線2 0、21流動 電流，藉由依該電流的焦耳熱熔化錫膠2 3，利用錫膠2 3 的表面張力與流動性進行連接。或是，也可併用紅外線燈 與焦耳熱熔化錫膠2 3進行連接。根據該連接方法可使短時 間的連接成為可能。另外，也可取代錫膠2 3而藉由導電性 環氧樹脂連接電極1 4、1 5與導電線2 0、2 1。在藉由導電 性環氧樹脂予以連接的情況，也可在將網眼狀構件3覆被 於太陽電池元件2後，藉由分配器將環氧樹脂吐出於所需 的部位，其後，由烘箱等加熱導電性環氧樹脂以使其硬化。 19 326\總檔\92\92130630\92130630(替換)-1 1255563 再者，將屬密封構件4的聚對二曱苯樹脂的覆被膜形成 於太陽電池元件2及網眼狀構件3等受光模組片1的全體 約1 0 0 // m的厚度。該密封構件4例如可藉由美國 Uni oncarbide and Plastic公司所開發的化學蒸鍵（CVD) 法的塗敷系統來形成。又，密封構件4並不限定於聚對二 曱苯樹脂，也可在液狀的狀態藉由吹塗、浸潰以成膜矽樹 脂、聚氣乙婦、聚酯（P E T )等的透明樹脂，並硬化而形成。 藉由如此之方法將密封構件4形成於受光模組片1，完成 受光模組片1。 再者，說明以上說明之受光模組片1的作用、效果。 根據該受光模組片1，因為太陽電池元件2具有連接於 球狀單結晶1 0的平坦面1 1的正電極1 4，與連接於η +型擴 散層1 2負電極1 5，因此在將太陽電池元件2組入受光模 組片1前可藉由太陽模擬器等檢查太陽電池元件2。藉此， 可僅將通過檢查的合格的太陽電池元件2組入受光模組片 1，可穩定製造高品質的受光模組片1。另外，利用組入前 而於太陽電池元件2形成正負電極1 4、1 5，可確實而簡單 連接電極1 4、1 5與導電線2 0、2 1，使得製造步驟亦變得 簡單。 因為網眼狀構件3編織入延伸於行方向的複數導電線 2 0、2 1及延伸於列方向的張力線材2 2，因此可實現具彎曲 性的受光模組片1，可實現強度優良的受光模組片1。尤其 是因為由輕的玻璃纖維構成張力線材2 2，因此可提升受光 模組片1的強度而可實現輕量化。 20 326\總檔\92\92130630\92130630(替換)-1 1255563 因為在太1¼電池元件2 ’在挟持太b電池元件2的中心 且位於對向的位置設有各電極1 4、1 5，因此，在太陽電池 元件2内產生的電流無偏向而對稱流動，可大幅削減電阻 損失，可輸出在太陽電池元件2的pn接面所發電的電力的 大致全部。而且，因為太陽電池元件2形成為球狀，因此 可接受來自全方向的入射光用以發電，可將該發電的電力 全部輸出，因此可提升發電效率。因為受光模組片1係由 彎曲的密封構件4所保護，因此可使其變形但不會使太陽 電池元件2及導電線2 0、2 1破損。 又，太陽電池元件2係構成為將在p型之球狀單結晶1 0 的表面部形成η型擴散層者作為主體，但也可為將在η型 之球狀單結晶的表面部形成ρ型擴散層者作為主體者。另 外，使用於太陽電池元件2的半導體並不限於矽，也可應 用 GaAs、GaAlAs、InP、InGaP、Ge、GaSb、InGaAs、I n G a N 等的半導體。 以下，簡單說明部分改變上述實施形態的例子。 1 )變化形態1 (參照圖1 0 ) 在該變化形態中，藉由與導電線的合金化接合連接未形 成電極的狀態下的太陽電池元件，以製造受光模組片1 A。 以下，說明該製造方法。 首先，製造圖8 (d )所示太陽電池元件，其次，由緩触刻 液完全除去氧化矽膜3 5，以製作太陽電池元件2 A。接著， 準備延伸於行方向的正極用導電線2 Ο A及負極用導電線 2 1 A，與延伸於列方向的編織入張力線材2 2的網眼狀構件 326\總檔\92\92130630\92130630(替換)-1 21 1255563 3 A。但是，兩導電線2 0 A、2 1 A係由含有1〜2 %可與矽作共 晶反應的石夕且直徑約為1 2 0 // m的紹線所構成。又，張力線 材2 2與上述實施形態的張力線材2 2相同緣故，省略其說 明。 再者，在與上述定位夾具41相同的定位夾具上配設多 數的太陽電池元件2 A，從此等上面覆被網眼狀構件3 A，使 兩導電線2 0 A、2 1 A與太陽電池元件2 A的平坦面1 1 (相當 於導電線連接部）及挾持太陽電池元件2 A的中心且與平坦 面1 1對向的部位（相當於導電線連接部）接觸。接著，在含 有數％的氫氣的氮氣的環境氣體中，在兩導電線2 0 A、2 1 A 流過數秒鐘的直流脈衝大電流進行焦耳加熱，藉由合金化 接合連接太陽電池元件2 A的平坦面1 1 A與正極用導電線 2 Ο A，同時，藉由合金化接合連接挾持太陽電池元件2 A的 中心且與平坦面1 1 A對向的部位的η+型擴散層1 2與負極 用導電線2 1 Α。又，藉由該合金化接合將形成於導電線 2 0 A、2 1 A與太陽電池元件2 A間的合金化區域作為電極 1 4 A、1 5 A進行工作。又，該合金化接合可在約5 7 0 °C〜6 5 0 °C的範圍内進行。在該合金化接合中，利用依脈衝電流的 急速加熱及急速冷卻，以防止鋁的擴散、或更深一步進行 合金化的情況，從而可實現良好的低電阻接觸（歐姆接 觸）。接著，在除去氧化矽膜36後，藉由CVD法在太陽電 池元件2 A上形成氧化矽膜或氧化鈦膜等的鈍化膜，在受光 模組片的全面形成密封構件4，完成受光模組片1 A。 又，作為導電線2 0 A、2 1 A，可取代鋁線而使用鎳（4 2 % )、 326\總檔\92\92130630\92130630(替換；hi 22 1255563 鐵（5 2 % )及鉻（6 % )的合金線（直徑為1 2 Ο // m )，也可在該合 金線與電極的接合部位覆被鋁或含有1〜2 %的矽的鋁合金 膜。在如此之構成的情況，也可藉由流過電流於合金線而 產生的焦耳熱，熔化鋁或鋁合金膜，以連接導電線2 Ο A、 21A與太陽電池元件2A。 該合金線因為與鋁線相比，其導電率、熱傳導率低，因 此，具有可以較少的電流進行接合，同時，提升拉伸強度 的優點。另一方面，也可取代鋁線而使用銅線作為導電線 2 0 A、2 1 A，並在該銅線的接合部位覆被金·矽合金、金· 鍺合金、金·錫合金等的合金膜，藉由流過電流於導電線 20A、21A而產生的焦耳熱，熔化此等合金膜，以連接導電 線2 0 A、2 1 A與太陽電池元件2 A。金合金可以較is低的溫 度進行依共晶反應的合金化接合。 根據該製造方法，因為沒有必要預先形成正負的電極， 因此可簡單進行太陽電池元件2 A與導電線2 0 A、2 1 A的連 接，因此可提高生產性，可削減製造成本。 2 )變化形態2 (參照圖1

又，利用聚碳酸酯或丙烯等的樹脂組成的透明板構件來 構成表面層4 5，可使受光模組片1 B低成本化及輕量化。 另外，也可由P B V (聚乙烯醇縮丁醛）、丙烯、矽等的透明 樹脂來構成緩衝層4 6。 如此般，藉由2個表面層4 5夾入太陽電池元件2及網 眼狀構件3予以構成，可提升對機械衝擊的強度，作為透 明型的受光模組片而可用作為窗玻璃。 另一方面，如圖1 2所示，也可構成受光模組片1 C的密 封構件4

以上），減少太陽電池元件2的溫度上升，以提升光電變換 效率。藉此，從受光模組片1 C的受光面（上面）入射的光， 首先藉由熱線反射膜5 5反射一部分不需要的熱線，剩餘的 光的一部分則由太陽電池元件2接受，一部分穿過太陽電 池元件2間，但該穿過的光藉由反射膜5 2的反射而由太陽 電池元件2接受。 又，也可取代PE系樹脂，而由聚碳酸酯、聚萘二甲酸 乙二醇酯、氟系樹脂等的彎曲性的合成樹脂所構成。也可

Description: [Technical Field] The present invention relates to an optical module sheet and a method of manufacturing the same, and more particularly to an insulating tension for electrically connecting a conductive wire of a spherical element and a fixed conductive wire The wire is woven into a mesh-like optical core piece. [Prior Art] At present, a solar cell that has been put into practical use has a planar pn junction by diffusing impurities on a planar semiconductor wafer or the like. In the solar cell configured as described above, the output of the solar cell is maximized when the light is incident on the light receiving surface vertically, but the output thereof also decreases as the incident angle of the light is inclined toward the light receiving surface. Therefore, since the solar cell having such a configuration has a strong directivity characteristic, it is difficult to use light efficiently, and since the crystal ingot of the semiconductor crystal is sliced to form a wafer, the processing loss by cutting or the like is large. It is also related to the increase in manufacturing costs. For the above reasons, it is disclosed in U.S. Patent No. 4,58,001, the disclosure of the disclosure of the entire disclosure of the entire disclosure of the entire disclosure of the disclosure of the entire disclosure of the disclosure of the disclosure of the disclosure of the entire disclosure of the disclosure of the entire disclosure of the disclosure of the entire disclosure of the entire disclosure of A solar cell element that forms a spherical pn junction and a solar cell module that connects the solar cell element with aluminum foil. The solar cell module does not form an independent electrode before modularizing the spherical solar cell element, but mechanically presses the solar cell element into the hole formed in one piece of aluminum foil to be electrically connected to the n-type surface. Sexually connecting, and then removing a part of the surface of the n-type layer of the solar cell element protruding downward from the hole by an etching treatment or the like to expose the p-type 作为 as a core, and the p-type 矽 is brought into contact with the surface of the other aluminum foil to form Positive electrode. The connection is made by having a majority of 6 326\total file \92\92130630\92130630 (replacement)-1, and the solar cell module is formed by two aluminum foils and the parallel connection between the solar cell elements. The characteristics of forming and parallel connection, the aluminum foil is exposed to the Ρ-type area, so it is difficult to have characteristics and good or not. In addition, it is limited to parallel connection, so it is to improve the solar cell module junction. If the interval between the solar cell and the foil is shortened, the manufacturing process of the aluminum foil is complicated. Because the current between the positive and negative cells is lower than the center of the positive and negative cell elements, that is, the current flowing between the positive and negative electrodes is not able to sufficiently improve the photoelectric conversion effect and the light-receiving surface is limited to the light in the direction of the I-lu, so that the current cannot be improved. The publication 9 - 1 6 2 4 3 No. 4 discloses that a wire pool of a plurality of spherical solar cell elements is supported by a stranded wire material and a glass fiber extending laterally, and the conductor wire is used to support the insulation between the solar body wires. -1 6 2 4 3 The solar energy described in the 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th, 4th To achieve modularity. If two aluminum foils are joined at the same time, but because of the connection between the n-type layer and the determination of each solar cell element, if the output voltage must be smaller than the diameter of the other components, the two sheets of insulation are required. This becomes difficult, so that the position of the electrode is in a position where the solar electrode is formed at an asymmetrical position, the position where the electrode is biased is short, the rate is equal, and the like, and the upper side of the aluminum foil has a disadvantage that it cannot be taken. The special purpose of this patent publication is to woven a glass fiber cloth formed by a longitudinally extending linear conductor to support a solar cell. The solar cell element is simply guided. However, in the battery element provided in the above-mentioned special-opening 9 tank, the 326\total file of the entire circumference is covered by the n-type layer (92) (replacement) -1 1255563 Material and P type area. Before the conductor wires and the solar cell elements are connected, since only the n-type layer is exposed to the outside, it is impossible to inspect each of the solar cell elements before the connection, and the same problems as those cited above are caused. Further, since the positive electrode conductor wire connected to the p-type region is also connected to the n-type layer, the electroless chemical etching treatment is performed by continuously irradiating light to perform pn junction isolation so that the positive electrode conductor wire is connected only to the p-type region, but Since the progress of the etching process varies in each solar cell element, it is difficult to surely perform pn junction isolation on all solar cell elements. Also in the solar cell element of this publication, since the positive electrode conductor and the negative electrode conductor are connected to the opposite center asymmetric position, the same problems as the above cited documents are also caused. Furthermore, when the solar cell element is replaced with a spherical light-emitting diode, the light is emitted only in a narrow region between the conductor wires, so that the light cannot be emitted in all directions, and the spherical light-emitting diode is lost. The problem of the advantages of the body. Here, as disclosed in the International Publication No. WO 0 8 / 1 5 9 8 3, the applicant proposes a plurality of spherical elements belonging to a solar cell element or a light-emitting element and an optical module sheet connecting the spherical elements. The spherical element includes a spherical p-type (or n-type) single crystal semiconductor (such as ruthenium); an n-type (or p-type) diffusion layer formed in the vicinity of the surface of the single crystal semiconductor; and a substantially spherical shape a pn junction; a pair of positive and negative electrodes disposed at an opposite position of the center of the spherical single crystal semiconductor. These plurality of spherical elements are arranged in a matrix of a plurality of rows and plural columns, and these are connected in series or in parallel to constitute an optical module sheet. Because in these spherical elements, there is an electric 3 2 6 \ total file \92\9213 063 0\9213063 0 (replacement) -1 8 1255563 pole in the opposite position holding the center, so it is used to directly contact the adjacent The positive electrode and the negative electrode of the spherical element are arranged in such a manner that a plurality of spherical elements can be simply connected in series, but it is not easy to connect the respective spherical elements in parallel. In order to improve the problem, the applicant of the present application has placed two conductive wires arranged in parallel in a state in which the directions of the electrodes are aligned to each other in the publication of the International Publication No. WO 03/0 1 7 3 8 2 . The positive and negative electrodes of the spherical element are connected in parallel to form a spherical element row, and the spherical element row is connected in series by a conductive line connecting the adjacent spherical element rows. However, in the optical module sheet, there is a problem that the tensile strength of the conductive wire in the longitudinal direction is strong, and the vertical direction is very weak, and the connection between the connecting spherical member and the conductive wire is simple to improve the production efficiency. necessary. It is an object of the present invention to provide an optical module sheet which can be composed only of qualified spherical elements; an optical module sheet having strong tensile strength; and an optical conversion or electro-optical conversion with high efficiency of providing a spherical element Optical module sheet; provides an optical module sheet that is easy to manufacture. Other objects of the present invention will be apparent from the description of the effects of the present invention and the description of the embodiments. SUMMARY OF THE INVENTION An optical module sheet of the present invention includes: a plurality of spherical elements, a plurality of spherical elements having a function of receiving or emitting light, each having a substantially spherical pn junction and respectively connected to a pn junction. The positive and negative conductive line connecting portions located at both ends of the spherical element at both poles are arranged in a matrix shape with the same polarity; the plurality of conductive lines arranged in parallel are for the respective spherical elements of the plurality of rows, and the plurality of spherical elements are arranged through the respective rows The positive and negative conductive wire connecting portions are electrically connected in parallel to the plurality of spherical elements of each row; and the insulating plural tension wire 326\total file\92\92130630\92] 30630 (replacement)-1 9 1255563 material, and the plurality of conductive materials The wires are arranged vertically between the columns and columns of the spherical element, and are woven into a mesh shape by fixing the plurality of conductive wires and the plurality of conductive wires. In the case of the light-receiving module sheet, light is incident on the light-receiving module sheet regardless of the incident direction of the light, and when the light polarities are uniformly incident on the plurality of spherical elements arranged in a matrix, they are formed in the spherical element. The substantially spherical pn junction receives light and is converted into electrical energy by the light receiving function of the spherical element. The electric energy is output to the outside via a positive and negative conductive line connecting portion which is connected to both ends of the p η junction and which are located at both ends of the spherical element. In the case of a light-emitting module piece, electric energy supplied from the conductive wire to the spherical element via the conductive wire connecting portion is converted into light energy by the pn junction of the spherical element, and the light is emitted to the outside. Since the spherical element has positive and negative conductive line connecting portions connected to the two poles of the pn junction, the spherical element can be inspected before the spherical element is incorporated into the optical module sheet, and as a result, only the qualified spherical element group can be selected. Into the optical module sheet, stable production of high quality. Further, by forming the positive and negative conductive line connecting portions in the spherical member before the assembly, the connection between the conductive line connecting portion and the conductive line is simplified, and the manufacturing steps are also simplified. Since the plurality of conductive wires extending in the row direction and the plurality of insulating tension wires extending in the column direction are woven into a mesh shape, the strength is excellent. Since the positive and negative conductive line connecting portions of the spherical element are connected to the substantially spherical pn junction and at both ends of the spherical element, the entire pn junction can be effectively applied, and the power and light generation efficiency can be improved. Here, in addition to the above configuration, the following configuration can be suitably employed. (1) In each of the spherical elements, the positive and negative conductive line connecting portions are located at positions facing each other at the center of the spherical element. 10 326\总档\92\92130630\92130630 (replacement)-1 1255563 (2) A transparent synthetic resin or a sealing member made of transparent glass is provided, which accommodates the plurality of spherical elements together with a plurality of conductive wires and a plurality of tension wires Buried state. (3) Each of the above spherical elements is a photodiode element or a solar cell element. (4) Each of the above spherical elements is a light emitting diode element. (5) The conductive wire is a one selected from the group consisting of solder, conductive synthetic resin, and alloy metal to connect the positive and negative conductive wire connecting portions. (6) The sealing member is buried so that at least a part of the above-mentioned electrically conductive wire is exposed. (7) An insulating tension wire woven in a conductive line in parallel with the conductive wire is provided between the row and the row of the spherical element. (8) The sealing member is a flexible member formed using a transparent synthetic resin material. (9) A reflecting film that reflects light incident from the incident side is formed on a surface opposite to the incident side of the light of the sealing member. (10) The sealing member is composed of a flexible transparent buffer layer in which a plurality of spherical elements are housed in a buried state, and a transparent surface layer joined to both surfaces of the buffer layer. (1 1) The sealing member has a heat reflecting film made of a polymer material which selectively reflects a heat ray which cannot be absorbed by the spherical element. (1 2) A series connection mechanism having a plurality of rows of electrically conductive wires in which a plurality of rows of the spherical elements are connected in series. 11 326\总档\92\92130630\92130630 (replacement)-1 1255563 The manufacturing method of the optical module sheet of the present invention includes a plurality of spherical elements and a matrix-shaped light-receiving or light-emitting function. a plurality of spherical elements; a conductive wire, a plurality of spherical elements electrically connected in parallel; and an insulating tension wire, which is a manufacturing method of an optical module piece in which a conductive wire is fixed and a conductive wire is woven into a mesh shape a step of manufacturing a spherical element having a spherical element having a positive and negative conductive line connecting portion; and a bonding member for connecting the spherical element and the conductive wire by Joule heat according to a current flowing through the conductive line The component connects the step of connecting the spherical element to the conductive wire. According to the manufacturing method of the optical module sheet, first, in the spherical element manufacturing step, a plurality of spherical elements having positive and negative conductive line connecting portions are manufactured, and secondly, in the connecting step, by melting according to a current flowing through the conductive line The bonding member connects in parallel a plurality of spherical elements and conductive lines arranged in a matrix in a matrix. Thereby, the spherical member can be inspected as a good or a bad product via the conductive wire connecting portion, and the spherical member of the defective product can be prevented from being incorporated into the optical module sheet. Further, by forming the positive and negative conductive line connecting portions in the spherical element before the assembly, the connection between the conductive line connecting portion and the conductive line becomes simple and simple, and the manufacturing steps are also simplified.

Therefore, only a brief explanation is given here. As shown in Fig. 1 and Fig. 2, a plurality of solar cell elements 2 have a light receiving function for converting light energy into electric energy, and are arranged in a matrix shape with the same polarity. For example, about 20,000 solar cell elements 2 are used for each watt of power generation output. As shown in FIG. 3, each solar cell element 2 has a resistivity of 0. The P-type single crystal 矽 composition with a degree of 3 to 1 Ω m has a diameter of about 0. 6~2. A spherical crystal 10 of 0 m is formed as a material. A flat surface 11 is formed at one end portion of the spherical crystal 10. An η + -type diffusion layer 12 (having a thickness of about 0) in which phosphorus (P) is diffused in the entire region is formed in substantially the entire region of the surface portion of the spherical crystal 10 other than the flat surface 1 1 . 4~0. 5 // m ), a substantially spherical p η junction 13 is formed on the boundary surface between the η + -type diffusion layer 12 and the p-type region. The diameter of the globular crystal 10 is about 1. In the case of 0 m m , the diameter of the flat surface 1 1 is approximately 0. 5 m m. However, the diameter of the flat surface 11 can also be 0. 5mm or less. A positive electrode 14 (corresponding to a conductive line connecting portion) is provided on the flat surface 1 1 , and a negative electrode 15 is provided at a position sandwiching the center of the spherical crystal 10 and facing the positive electrode 14 (corresponding to a conductive line) Connection)). The positive electrode 14 is connected to the p-type region of the spherical crystal 10, and the negative electrode 15 is connected to the n + -type diffusion layer 12. 326\Total file\92\92130630\92130630 (replacement)-1 13 1255563 The positive electrode is formed by sintering aluminum paste, and the negative electrode is formed by sintering silver paste. An anti-reflection film 16 (having a thickness of about 0) composed of an insulating film of S i 〇 2 (or T i 0 2) is formed on the entire surface except the positive electrode 14 and the negative electrode 15 . 6~0. 7 // m ). The solar cell element 2 has a light receiving function which receives sunlight and generates 0 between the electrodes 14 and 15. 5~0. 6 V light starts from electricity. As shown in Fig. 2, Fig. 4, and Fig. 5, the mesh member 3 has a positive electrode wire 20, a negative electrode conductive wire 21, and a glass fiber tension wire 221. The conductive wire 20, 2 1 is a wire having a diameter of 120/zm composed of an alloy of nickel (4.2%), iron (52%) and chromium (6%), and a key tin layer is formed on the surface thereof. 2~3 // m ) 〇 As shown in FIG. 2, the two conductive wires 20 and 2 1 extend in parallel in the row direction, and the positive conductive wires 20 and the negative conductive wires of the respective rows of the adjacent solar cell elements 2 are adjacent. The centerline of 2 1 is approximately 0. The distance between the solar cell element 2 of each row of 7 5 m in ^ rows and the center of the solar cell element 2 adjacent to the row is about 1. 75mm. The positive electrode conductive wire 20 is electrically connected to the positive electrode 14 via the tin paste 2 3 , and the negative electrode conductive wire 21 is electrically connected to the negative electrode 15 via the tin paste 2 3 . The plurality of rows of solar cell elements 2 are electrically connected in parallel by two conductive wires 20' 2, and the solar cell elements 2 of all rows are electrically connected in series. However, this will be detailed later. Further, the conductive wire is not limited to the above-described constituents, and may be iron, iron (58%), nickel (42%) alloy wire, other iron alloy wire, copper wire, beryllium copper wire, phosphor bronze wire, or other copper. Alloy wire, silver, silver alloy wire, nickel, nickel alloy wire, etc., can also be composed of a twisted wire made of thin wires made of such materials, and electrical, mechanical, chemical properties, etc. can be considered. . In this case, 14 326\total file\92\92130630\92130630 (replacement)-1 1255563 Especially the wire of the beryllium copper wire or the phosphor bronze wire has elasticity, so that the contact with the solar cell element 2 can be surely maintained. The tension wire member 2 2 is disposed between the solar cell element 2 of each row and the solar cell element 2 of the adjacent row so as to extend in the column direction so as to be perpendicular to the conductive wires 20 and 21. Each of the tension wires 2 2 is made of 7 glass fibers (the diameter is about 9 . 0 / m) is formed, these three tension wires 2 2 as a group, with a pitch of about 1. The interval of 7 5 m is arranged between the columns. For fixing the conductive wires 20 and 2, each tension wire 2 2 is sewed into the two conductive wires 20 and 21, and a plurality of conductive wires 20 and 21 and a plurality of tension wires 2 2 are woven. The mesh is formed in a mesh shape to form a mesh member 3. As shown in FIG. 6, the sealing member 4 is formed to protect a plurality of solar cell elements 2 and mesh-like members 3 for forming a plurality of too 1% battery elements 2, conductive wires 20, 2 1 and tension wires. 2 2 Contained in a buried state. The sealing member 4 is formed into a sheet shape having a thickness of about 100 μm using an insulating transparent polyethylene terephthalic resin. The polypara-phenylene benzene resin has the following advantages: that is, it is possible to perform uniform coating with less pinholes in the fine portion, less permeability of gas or water vapor, high stability to radiation, and refractive index (about For 1 . 6 1 ) Features such as high reflection loss to the surface of the solar cell element 2, and the like. Thereby, the sealing member 4 can be formed in a state of being thinly covered on the surface of the solar cell element 2, and therefore has a wide directivity for receiving light, a small reflection loss, and is lightweight, stretched, or bent due to its flexibility. The advantages of increased strength and high light collection efficiency. According to the light-receiving module sheet 1, light is incident on the light-receiving module sheet 1 regardless of the incident direction of the light, and the light polarity is uniformly incident on the 326\total file\92\92130630\92130630 (replacement) arranged in a matrix. -1 15 1255563 When the plurality of spherical elements 2 are received, light is received by the substantially spherical pn junction 13 formed in the solar cell element 2, and is converted into electric energy by the light receiving function of the solar cell element 2. This electric energy is outputted to the outside through the opposite positive and negative electrodes 14 and 15 which are connected to the center of the solar cell element 2 via the two poles of the p η junction 13 . Next, Fig. 7 shows an equivalent circuit 30 of the solar cell module included in the light receiving module sheet 1. The equivalent circuit 30 is, for example, converted into a matrix 3 1 of a plurality of matrix-shaped solar cell elements 2 arranged in a plurality of rows and columns. The diodes 3 1 (solar cell elements 2) of the respective rows of the equivalent circuit 30 are connected in parallel by the positive conductive wire 20 and the negative conductive wire 21, and further, the positive electrodes of the respective rows are used. The conductive wire 20 is connected in series to the negative conductive wire 2 of the adjacent row by the conductive wire 34 in series. The output of one solar cell element 2 is 0. 6 V, the number of columns is m and the number of rows is η, and about η X 0 is generated between the positive terminal 3 2 and the negative terminal 3 3 . 6 V light starts from electricity. When the current generated in one solar cell element 2 is 1, the current of m X I is output from the positive terminal 3 2 to the external load. In this manner, a plurality of solar cell elements 2 are connected in series and in parallel, and even if light is not incident on a part of the light receiving module sheet 1, a part of the solar cell elements 2 are in a state in which power generation is impossible because they flow through the other solar cell elements 2. Current, so the effect of output reduction can be kept to a minimum. Furthermore, a method of manufacturing the light-receiving module sheet described above will be described. First, a method of manufacturing the solar cell element 2 of the present invention will be described with reference to Fig. 8, but the manufacturing method is based on the international publication W 0 9 8 / 1 5 9 8 3 and W 0 0 3 / 0 applied by the applicant of the present application. 3 6 7 3 No. 1 has a detailed description, so here only 16 326 \ total file \92\92130630\92130630 (replace)-1 1255563 for a brief description. First, the broken droplets in a molten state are freely dropped in each amount, and a rapid solidification by supercooling on the way to form a diameter of about 1. A p-type spherical single crystal 10 of 0 m m is mechanically ground to form a flat surface 1 1 of a spherical single crystal 10 (see Fig. 8 (a)). Next, the spherical single crystal 10 is heated in oxygen containing about 1000 ° C of water vapor for about 40 minutes to form a thickness of about 0. 3 μm of yttrium oxide film 3 5 (refer to Figure 8 (b)). Next, in order to cover the yttrium oxide film 35 as a thermal diffusion impurity (n-type impurity) only in a desired region, the acid-resistant paraffin wax is melted into a uniform thickness on the glass plate, and the flat surface 11 is abutted. Pressed on the surface of the paraffin to solidify the paraffin. Next, it is immersed in a slow etching solution (aqueous solution of Ν 4 HF 2 ), and only the cerium oxide film 3 exposed from the solidified wax is removed by etching, and then the spherical single crystal 10 is removed from the glass plate. Remove the paraffin (see Figure 8 (c)). Further, the spherical single crystal 10 is heated at about 960 ° C for about 3 minutes in a nitrogen carrier gas which vaporizes the phosphorus oxychloride (Ρ 0 C 13) liquid, and no ruthenium oxide film is formed. The surface of the spherical single crystal 10 forms a phosphonium phosphate glass film 3 6, and further, it is converted into oxygen which is dried by the ambient gas, and is heated to about 9 8 (TC, 60 seconds, and the n-type impurity (phosphorus) is heated. The inside of the vicinity of the surface of the spherical single crystal 10 is diffused. The n-type impurity is diffused in this manner, and the n + -type diffusion layer 12 is formed on the flat surface 11 covered by the tantalum oxide film 35 of the mask. At the same time, a portion other than the vicinity thereof forms a p η junction 1 3 at the boundary between the n + -type diffusion layer 12 and the p-type region of the spherical single crystal 10 (see Fig. 8 (d)). The ruthenium oxide film 35 outside the flat surface 1 1 and its vicinity is removed by the slow etching solution, and again heated in dry oxygen at about 80 ° C for 60 seconds at 17 326 \ total speed, \92\92130630 \92130630(Replacement)-1 1255563 The spherical anti-reflection film 16 (see Fig. 8(e)) which is also a passivation film composed of a ruthenium oxide film formed on the entire surface of the spherical single crystal 1 ( (see Fig. 8(e)). 4 On the flat surface, the aluminum paste 3 7 is printed on the flat surface, and the n + -type diffusion layer 12 is formed at a portion where the center of the spherical single crystal 10 and the flat surface 11 is opposed to the negative electrode 15 is formed. The surface-point printing silver paste 3 8 is heated in a nitrogen gas at about 80 (TC is heated to treat the spherical single crystal 10 in this state for about 60 minutes, and the aluminum rubber 37 and the silver paste 38 penetrate the anti-reflection film 16. And the gelatin 3 7 and the p-type region 5 of the spherical early crystal 10 are in low-resistance contact (ohmic contact) with the n-type diffusion layer 12, respectively, and the solar cell element 2 is completed (refer to FIG. 3). The voltage-current characteristic of the completed solar electronic component 2 is measured by light irradiation of a solar analog light source to select the solar cell element 2 as a good product and a defective product. Further, as shown in FIG. In the battery element 2, a quartz positioning jig 4 1 in which the positioning holes 40 are formed at predetermined intervals is prepared. Next, the directions in which the electrodes 14 and 15 are aligned (the polarities of the electrodes 14 and 15) are determined to be qualified solar cells. The element 2 is disposed in the positioning hole 40 of the positioning jig 4 1. Also, since the solar cell element 2 is formed with a flat surface 11 Therefore, the positive and negative electrodes 14 and 15 can be easily identified, and the directions of the electrodes 14 and 15 can be easily aligned. The equator line disposed on the horizontal surface of the solar cell element 2 of the positioning jig 4 1 and The upper surface of the positioning jig 41 is substantially the same height. Next, in order to prevent the movement or rotation of the solar cell element 2, the inside of the positioning hole 40 is decompressed to fix the solar cell element 2 to the positioning hole 40. Further, in the positioning jig 41 Upper 18 326\main file\92\92130630\92130630 (replacement)-1 1255563 The surface is coated with carbon or boron nitride film so as not to be bonded to the bonding material of tin paste 2 or the like. Next, the mesh-like member 3 which is woven into the conductive wires 20 and 21 and the tension wire member 2 is prepared, and the tin paste 2 3 is applied to the positive electrode of the mesh member 3 by dot printing or discharge of the dispenser. The conductive wire 20 is connected to the portion where the positive electrode 14 is connected, the negative conductive wire 21, and the portion where the negative electrode 15 is connected, and the mesh member 3 is covered with the sun fixed to the positioning jig 4 1 from above. On the battery element 2. Next, the mesh member 3 is brought into close contact with the upper surface of the positioning jig 41 by a pressing jig (not shown), and the tin paste 2 3 and the electrodes 14 and 15 covered on the conductive wires 20 and 21 are simultaneously adhered. Close contact. Next, in a state in which a plurality of solar cell elements 2 and mesh-like members 3 are placed on the positioning jig 4 1 , a poly-beam of the infrared lamp is irradiated to the tin gel 2 3 to melt the tin-gel 2 3 by the tin-gel 2 3 The conductive line 20 and the electrode 14 are electrically connected, and the conductive line 2 1 and the electrode 15 are electrically connected. Further, the flux contained in the tin paste 2 3 is removed by washing and dried. Further, as another connection method, a current may flow through the conductive wires 20 and 21, and the tin rubber 2 may be melted by the Joule heat of the current, and the surface tension of the tin gel 2 3 may be connected to the fluidity. Alternatively, an infrared lamp may be used in combination with the Joule hot melt solder paste 2 3 . According to this connection method, a short-time connection can be made possible. Alternatively, the electrodes 14 and 15 and the conductive wires 20 and 21 may be connected by a conductive epoxy resin instead of the tin gel 2 3 . In the case of being connected by a conductive epoxy resin, after the mesh member 3 is covered by the solar cell element 2, the epoxy resin may be discharged to a desired portion by a dispenser, and thereafter, The conductive epoxy resin is heated in an oven or the like to be hardened. 19 326\总档\92\92130630\92130630 (replacement)-1 1255563 Further, the coating film of the polyparaphenylene resin which is the sealing member 4 is formed on the light receiving mode such as the solar cell element 2 and the mesh member 3. The total thickness of the group 1 is about 1.00 m. The sealing member 4 can be formed, for example, by a chemical vapor bonding (CVD) coating system developed by Uni oncarbide and Plastics, U.S.A. Further, the sealing member 4 is not limited to the polyparaphenylene resin, and may be formed by a blow coating or impregnation in a liquid state to form a transparent resin such as a resin, a gas, or a polyester. And hardened to form. The sealing member 4 is formed on the light receiving module sheet 1 by such a method, and the light receiving module sheet 1 is completed. Furthermore, the action and effect of the light receiving module sheet 1 described above will be described. According to the light receiving module sheet 1, since the solar cell element 2 has the positive electrode 14 connected to the flat surface 11 of the spherical single crystal 10 and the negative electrode 15 connected to the n + -type diffusion layer 12, The solar cell element 2 can be inspected by a solar simulator or the like before the solar cell element 2 is incorporated in the light receiving module sheet 1. Thereby, only the qualified solar cell elements 2 that have passed the inspection can be incorporated into the light receiving module sheet 1, and the high-quality light receiving module sheet 1 can be stably manufactured. Further, by forming the positive and negative electrodes 14 and 15 in the solar cell element 2 before assembly, the electrodes 14 and 15 and the conductive lines 20 and 2 can be reliably and simply connected, so that the manufacturing steps can be simplified. Since the mesh member 3 is woven into the plurality of conductive wires 20 and 21 extending in the row direction and the tension wires 2 2 extending in the column direction, the light-receiving module sheet 1 having flexibility can be realized, and the strength can be excellent. Light receiving module sheet 1. In particular, since the tension wire member 2 is composed of light glass fibers, the strength of the light receiving module sheet 1 can be improved, and the weight can be reduced. 20 326\总档\92\92130630\92130630 (replacement)-1 1255563 because the battery element 2' is provided with the electrodes 14 and 15 at the center of the battery element 2 and at the opposite position. Therefore, the current generated in the solar cell element 2 flows symmetrically without deflection, and the resistance loss can be greatly reduced, and substantially all of the electric power generated by the pn junction of the solar cell element 2 can be output. Further, since the solar cell element 2 is formed in a spherical shape, incident light from all directions can be accepted for power generation, and all of the electric power generated can be outputted, thereby improving power generation efficiency. Since the light receiving module piece 1 is protected by the curved sealing member 4, it can be deformed without breaking the solar cell element 2 and the conductive wires 20, 21. In addition, the solar cell element 2 is configured such that an n-type diffusion layer is formed on the surface portion of the p-type spherical single crystal 10, but the surface portion of the n-type spherical single crystal may be formed. The type of diffusion layer is the subject. Further, the semiconductor used for the solar cell element 2 is not limited to germanium, and a semiconductor such as GaAs, GaAlAs, InP, InGaP, Ge, GaSb, InGaAs, or n n G a N may be used. Hereinafter, an example in which the above embodiment is partially changed will be briefly described. 1) Modification 1 (see Fig. 10) In this modification, the solar cell element in a state in which the electrode is not formed is joined by alloying and bonding to the conductive wire to manufacture the light-receiving module sheet 1A. Hereinafter, the manufacturing method will be described. First, the solar cell element shown in Fig. 8 (d) was produced, and second, the hafnium oxide film 35 was completely removed by the slow-touch etching to prepare the solar cell element 2 A. Next, the conductive wire 2 Ο A for the positive electrode and the conductive wire 2 1 A for the negative electrode extending in the row direction, and the mesh member 326 of the braided tensile wire 2 2 extending in the column direction are prepared, and the total file is \92\92130630\ 92130630 (replacement) - 1 21 1255563 3 A. However, the two conductive wires 20 A and 2 1 A are composed of a ray having a diameter of 1 to 2 % which can be eutectic with ruthenium and having a diameter of about 1 2 0 // m. Further, the tension wire member 2 2 is the same as the tension wire member 2 2 of the above-described embodiment, and the description thereof is omitted. Further, a plurality of solar cell elements 2 A are disposed on the same positioning jig as the positioning jig 41, and the mesh-like members 3 A are covered from above, so that the two conductive wires 2 0 A, 2 1 A and the solar cell are provided. The flat surface 1 1 of the element 2 A (corresponding to the conductive line connecting portion) and the portion of the center of the solar cell element 2 A that is opposed to the flat surface 11 (corresponding to the conductive line connecting portion) are in contact with each other. Next, in an atmosphere of nitrogen containing a small amount of hydrogen gas, Joule heating is performed by flowing a large current of a DC pulse for several seconds on the two conductive lines 20A, 2 1 A, and the solar cell element 2A is joined by alloying bonding. The flat surface 1 1 A and the positive conductive wire 2 Ο A, and the n + -type diffusion layer 1 2 at the portion facing the center of the solar cell element 2 A and facing the flat surface 1 1 A by alloying bonding Conductive wire 2 1 与 with the negative electrode. Further, the alloyed region formed between the conductive lines 2 0 A, 2 1 A and the solar cell element 2 A is operated as the electrodes 1 4 A and 1 5 A by the alloying bonding. Further, the alloying bonding can be carried out in the range of about 570 ° C to 65 ° C. In this alloying joining, rapid heating and rapid cooling by a pulse current are used to prevent diffusion of aluminum or alloying further, thereby achieving good low-resistance contact (ohmic contact). Then, after removing the hafnium oxide film 36, a passivation film such as a hafnium oxide film or a titanium oxide film is formed on the solar cell element 2 A by a CVD method, and the sealing member 4 is formed on the entire light receiving module sheet to complete the light receiving module. Slice 1 A. Further, as the conductive wires 20A, 21A, nickel (4 2 %), 326\total file\92\92130630\92130630 (replacement; hi 22 1255563 iron (52%) and chromium can be used instead of the aluminum wire. (6 % ) of the alloy wire (diameter: 1 2 Ο // m ), or an aluminum alloy film containing 1 to 2 % of bismuth may be coated on the joint portion of the alloy wire and the electrode. In other cases, the aluminum or aluminum alloy film may be melted by Joule heat generated by flowing an electric current to the alloy wire to connect the conductive wires 2 Ο A, 21A and the solar cell element 2A. The alloy wire is compared with the aluminum wire. The conductivity and the thermal conductivity are low, so that it has the advantage of being able to join with less current and at the same time improving the tensile strength. On the other hand, instead of the aluminum wire, a copper wire can be used as the conductive wire 2 0 A, 2 1 A, an alloy film such as a gold-niobium alloy, a gold-niobium alloy, or a gold-tin alloy is coated on the joint portion of the copper wire, and Joule heat generated by flowing current through the conductive wires 20A and 21A is melted. An alloy film to connect the conductive wires 20 A, 2 1 A to the solar cell element 2 A. The gold alloy can enter the temperature lower than the is Alloying bonding by eutectic reaction. According to this manufacturing method, since it is not necessary to form positive and negative electrodes in advance, connection of the solar cell element 2 A to the conductive wires 20A and 2 1A can be easily performed, thereby improving productivity. The manufacturing cost can be reduced. 2) Modification 2 (Refer to Fig. 1 1 and Fig. 1 2) Next, a modification of changing the sealing member will be described. As shown in Fig. 11, the light receiving module sheet 1 B can also be constructed. In the light-receiving module sheet 1 B, the sealing member 4B has a flexible buffer layer 46 that accommodates the solar cell element 2 and the mesh-like member 3 in a buried state; and is bonded to the buffer layer 46. A transparent surface layer 45 on the upper and lower sides. The surface layer 45 is composed of a transparent white plate tempered glass plate having a thickness of about 2 mm. In the case of manufacturing the light-receiving module sheet 1 B, a surface layer 45, EVA (B 23 326 \ total file \92\92130630\92130630 (replacement)-1 1255563 ene-ethylene acetate) sheet, bonded with a solar cell The mesh member 3, the EVA sheet, and the surface layer 45 of the element 2 are superposed in this order, and are heated by vacuum evacuation in the layering apparatus to melt the EVA sheet, and the EVA melt is filled in the upper and lower surface layers 4 Five of the buffer layers 4 are used to fix the solar cell element 2 and the mesh member 3 by the buffer layer 46. Further, the surface layer 45 is formed of a transparent plate member made of a resin such as polycarbonate or propylene, and the light-receiving module sheet 1 B can be reduced in cost and weight. Further, the buffer layer 46 may be formed of a transparent resin such as P B V (polyvinyl butyral), propylene or hydrazine. In this manner, the solar cell element 2 and the mesh member 3 are sandwiched between the two surface layers 45, and the strength against mechanical impact can be enhanced, and it can be used as a window glass as a transparent light receiving module piece. On the other hand, as shown in Fig. 12, the sealing member 4 C of the light receiving module piece 1 C may be formed. The sealing member 4 C of the light-receiving module sheet 1 C is composed of a reflective film 5 of a PE film (polyester) resin film 50, an aluminum vapor-deposited film 5 1 , and a multilayer film of a PE-based resin, which are embedded in a flexible layer from the lower layer. 2. The solar cell element 2 of the EVA resin and the filling material 53 having the same buffer layer as the mesh member 3, the PE-based resin layer 504, the heat-ray reflecting film 55, and the PE-based resin layer 56. The reflective film 52 is formed on a surface opposite to the incident side of the light to reflect and scatter light incident from the incident side and passing between the solar cell elements 2 to illuminate the solar cell element 2 to improve light utilization. Efficiency and increase power generation efficiency. The heat reflecting film 5 5 is composed of a multilayered polymer material having a different refractive index. The hot wire reflecting film 5 5 selectively reflects the hot wire which cannot be absorbed by the solar cell element 2 by multi-layer interference (wavelength 1 3 5 0 mm 24 326\total file\92\92130630\92130630 (replacement)- 1 1255563 or more), the temperature rise of the solar cell element 2 is reduced to improve the photoelectric conversion efficiency. Thereby, light incident from the light receiving surface (upper surface) of the light receiving module sheet 1 C is first reflected by the heat reflecting film 55 to form a part of the unnecessary hot line, and a part of the remaining light is received by the solar cell element 2, and a part of the light is received. The solar cell elements 2 pass, but the passing light is received by the solar cell element 2 by reflection of the reflective film 52. Further, it may be composed of a flexible synthetic resin such as polycarbonate, polyethylene naphthalate or a fluorine resin instead of the PE resin. Instead of the E V A resin, ruthenium or polyvinyl butyral resin or the like may be used as the filler 53. The reflection film 52 and the heat ray reflection film 55 can be omitted as appropriate, and other layers can be appropriately changed in accordance with the desired functions. 3) Variation 3 As for the method of manufacturing the light-receiving module sheet, a double drum method can also be used. In the case of the production by the double-rolling method of the roll, the heat-resistant resin film such as a polyimide film may be fixed to both end portions in the width direction of the mesh member, and the sprocket hole may be provided in the heat-resistant resin film. The sprocket hole is coupled to the sprocket to transfer or take up the structure of the mesh member. 4) Modification 4 In the above embodiment, the spherical element is a light receiving module piece of the solar cell element. However, the spherical element is not limited to the solar cell element, and a spherical photodiode or a light emitting diode may be applied. Polar body. Further, the spherical photodiode or the light-emitting diode has substantially the same configuration as the solar cell element 2 described above, and the detailed description of the international W 0 9 8 / 1 5 9 8 proposed by the applicant of the present application is described in detail. Since it has been described in the 3rd bulletin, detailed description is omitted. In the case of a light-emitting module piece having a light-emitting diode of 25 326\total file\92\92130630\92130630 (replacement)-1 1255563, when the current flows in the forward direction of the light-emitting diode, the pn junction will be used The electric energy is converted into light energy, and light having a wavelength in response to the crystal or the diffusion layer material is generated from the vicinity of the pn junction, and is irradiated to the outside. In the light-emitting module sheet composed of the spherical photodiode, the light can be irradiated in all directions, and a part of the reflective film can be provided to irradiate light only in a desired direction. Further, the three-color light-emitting diode of R G B may be arranged in a matrix, and the configuration of the light-emitting diodes may be controlled by the control device, or the light-emitting module sheet may be used as a color display. Further, a monochrome display can be constructed by a single-color light-emitting diode. In the light receiving module sheet composed of the photodiode, the omnidirectional light can be converted into an electrical signal. 5) Modification 5 In the above embodiment, an example in which solar cells of all rows are connected in series has been described. However, a plurality of switches capable of changing the number of rows connected in series may be provided, depending on the intensity of light or the amount of electric power required. The configuration of the plurality of switches is switched by the control device. 6) Modification 6 In the above embodiment, the sealing member is provided. However, the sealing member may not necessarily have a conventional configuration and may be omitted as appropriate. The present invention is not limited to the embodiments described above, and various modifications and improvements can be made to the above-described embodiments without departing from the spirit and scope of the invention.

In the above embodiment, the 3 26 3 2 6\the total file \92\9213 063 0\9213 063 0 (replacement)-1 1255563 tension wire 2 2 is arranged as a group in the column and the space of the solar cell element 2 However, the number of the tension wires is not necessarily limited to three, and the configuration may be required, and one or a plurality of roots may be arranged as a group. The tension wire may be composed of a high-strength synthetic resin or ceramic such as an insulating aromatic polyamide fiber. With such a configuration, the flexibility and tensile strength of the optical module sheet can be increased, and at the same time, the light-receiving module sheet 1 D can be reduced as shown in Fig. 13, and not only an insulating sheet can be used. 22 is perpendicular to the conductive line, and the tension wire 22a is disposed between the rows of the cell elements so as to be woven into a direction parallel to the conductor line in such a manner that the tensile strength in the direction in which the conductor wire extends can be increased. In Fig. 13, the same components as those in the embodiment are denoted by the same reference numerals, and their description will be omitted. 8) Modification 8 In the above embodiment, the positive and negative conductive wires are provided in each row. Alternatively, the conductive wires for the positive electrode and the conductive wires for the negative electrode may be used together with one conductive wire. With such a configuration, the series wires can be omitted and simply configured to reduce the interval between the rows and to shape the optical module. 9) Modification 9 In the above embodiment, the spherical solar cell element 2 is shaped like a flat surface, but the solar cell element omitting the flat surface 1 1 may be applied as described above. The composition of the positive and negative electrodes can be easily identified in order to change the shape of the positive and negative electrodes. 326\总档\92\92]30630\92130630 (replacement)-1 27 The appropriateness of the column can be extracted into the b-line, the Yangdian 〇利 and the _ symbol, but the style is small and flat.
