いる。 WESpear and others discovered that the conductivity of amorphous silicon obtained by plasma decomposition of silane (SiH 4 ) could be greatly changed by doping it with PH 3 or B 2 H 6 (1976). Since solar cells using amorphous silicon were prototyped by Carlson et al. (1976), they have attracted attention, and research has been actively conducted to improve the efficiency of amorphous silicon thin-film solar cells.

光の吸収ロスが大きい点に問題があつた。 In the case of pin junction type solar cells, p-type or n-type amorphous silicon has a short carrier life and is not an effective carrier, and the light absorption coefficient is larger than that of the i-layer, so light in the p-layer is The problem was that the absorption loss was large.

A pin-type photoelectric element has been proposed. i.e. n
This is an element that irradiates light from the amorphous silicon side. This element is considered to be somewhat advantageous because it has a relatively small light absorption coefficient compared to the p-type element. However, this n-type amorphous silicon is no different from the p-type in that there is light absorption loss.

That is, the present invention uses a mixture of at least one gas selected from silane or its derivatives, fluorinated silane or its derivatives, and at least one gas selected from nitrogen hydrides such as ammonia and hydrazine to plasma. It was discovered that the efficiency can be greatly improved by using a doped thin film of amorphous silicon nitride obtained by decomposition in at least one of the p or n layer of a pin junction photoelectric device, and it can be used in solar cells, optical switches, etc. It can be used as a photoelectric element.

等の電子分光によつて求める事ができる。 The amorphous silicon nitride of the present invention can be produced from at least one gas of a silicon compound selected from silane or its derivative, fluorinated silane or its derivative, and a hydrogen hydride of nitrogen such as ammonia or hydrazine. It is obtained by plasma decomposition of a mixture with at least one selected gas. The above silicon compounds include silane SiH 4 or a silane derivative represented by Si o H 2o+2 , or a derivative represented by SiF n H 4-n (m=1 to 4) and Si o F n H 2o+2- Examples include silicon hydrogen and/or fluoride represented by the derivative represented by n . In short, the silicon source for obtaining amorphous silicon nitride is a hydrogen and/or fluorine derivative of Si that has a vapor pressure, and the nitrogen source is a hydride of N that has a vapor pressure. It can be anything as long as it exists. Needless to say, it may be used after being diluted with hydrogen or an inert gas if necessary. Regarding the composition of amorphous silicon nitride, we used the composition of the film obtained by glow discharge decomposition.
The ratio of the number of Si atoms to the number of N atoms is expressed as a-Si (1-X) N (X) .
For example, when the ratio of N atoms to Si atoms in the film is 1:1, it is expressed as a-Si (0.5) N (0.5) . The composition ratio of N atoms and Si atoms in the film is IMA, SIMS, Augier, Esca,

Specifically, when producing a-Si (1-X) N (X) , PH 3 is mixed with, for example, silane and ammonia and then decomposed by glow discharge. The doping concentration may be controlled so that the electrical conductivity at room temperature is approximately 10 -7 (Ω·cm) -1 or more, preferably 10 -6 (Ω·cm) -1 or more. Usually about a-Si (1-X) N (X)

Glow discharge decomposition is performed using a high frequency of 14.56MHz using a quartz reaction tube with an inner diameter of 11cm. I-type a-Si is obtained by glow discharge decomposition of silane diluted with hydrogen at 2 to 10 Torr. N-type a-Si is made of silane diluted with hydrogen and phosphine (PH 3 ) (PH 3 /SiH 4 = 0.5

善がなされているのである。 Figure 2 shows the solar cell characteristics depending on the film composition of p-type a-Si (1-X) N (X) . As you can see from this figure, silane
In the case of 100% (Si 1 N 0 ), the conversion efficiency (hereinafter referred to as η) is 4.6%, whereas the a-Si (1-X) of the present invention
When N (X) is used, even when X = 0.05, it increases to η = 5.45%,
At X=0.2, it is improved to η=6.5%. When X=0.4, η=6.75%, which is an extremely high value compared to when silane is 100%. The point to note here is a.
-Si (1-X) N (X) has a larger optical forbidden band than a-Si, so although it is natural that the short circuit current (Jsc) will increase, the increase in the open circuit voltage (Voc) is unexpected. These improvements in efficiency have been achieved by improving both of these aspects.

できたものと考えられる。 The efficiency tends to decrease when X is 0.5 or more, but this is due to a decrease in the film factor (hereinafter referred to as FF) due to the increased resistance of p-type a-Si (1-X) N (X ). , the short circuit current Jsc and the open circuit voltage Voc are almost unchanged, and by using the a-Si (1-X) N (X) of the present invention, Jsc increases and the open circuit voltage decreases due to the reduction of optical absorption loss in the p layer. It is thought that the efficiency was improved by increasing the voltage Voc.

−Si (1-X) N (X) is decomposed and deposited by 100 Å glow discharge. a-Si is silane SiH 4 , a-Si (1-X) N (X) is
Glow discharge decomposition was performed using SiH 4 and NH 3 , respectively.
Furthermore, ITO was deposited by electron beam evaporation and the solar cell characteristics were similarly investigated. The figure shows the solar cell characteristics when the atomic fraction Shown in 3. Jsc increases almost continuously until X reaches 0.4, and FF and Voc also increase. On the other hand, since FF decreases when X>0.3, η also decreases, but when X=0.2, the conversion efficiency is improved to 6.5%. In the case of n-type a-Si (X=0 in FIG. 3), η=4.9%, which shows a significant improvement between X=0.05 and 0.95.
