Specific embodiment
Embodiment
Step 1) prepare electrode
By taking pulsed laser deposition as an example, or other methods, such as magnetron sputtering, sol-gel process etc..With La0.7Sr0.3MnO3As a example by bottom electrode, it would however also be possible to employ other materials, such as conductive oxide ITO, La0.5Sr0.5CoO3Deng Or metal, Au, Pt, Ag etc..First in SrTiO3Substrate (can certainly be other types of substrate, silicon chip, glass etc.) Cleaned with ultrasound wave in acetone, ethanol respectively, dried；Chip bench is polished with sand paper, and cleaned up, will be dried in the air Dry substrate heat conduction elargol is bonded on chip bench, the corresponding mask of shape then according to required electrode, size, number Version blocks substrate.It is put into after drying in cavity on warm table, starts evacuation.Treat that air pressure is extracted into 10-4During Pa, substrate is begun to warm up Platform.Note being slowly heated, being generally heated to 700 DEG C needs 90 minutes or so.After reaching target temperature, substrate is kept off with baffle plate Firmly, and desired gas are passed through to certain pressure intensity.The energy and frequency parameter of setting laser, carries out pre-sputtering to remove La0.7Sr0.3MnO3Thin film is (here with La0.7Sr0.3MnO3：Bottom electrode as measurement photovoltaic effect is abbreviated as a example by LSMO, Other conductive films can be selected) dirt on surface, make thin film expose fresh surface, generally 2～5 points of pre-sputtering time Clock；During pre-sputtering, the parameter such as adjustment laser optical path, range, so that plumage brightness end is tangent with chip bench.Rotate chip bench and Thin film, and laser is made in X, Y-direction particles；After treating temperature, stable gas pressure, baffle plate is removed, deposited.According to required Film thickness select suitable sedimentation time, deposition to terminate after, be filled with certain gas slow cooling as required.
The leg in covering substrate is taken, the leg includes side wall, roof, and the burning/decomposition temperature of the leg is low In the burning/decomposition temperature of ferroelectric material, the material of leg is using Organic substance thin slice (or the thin film that other materials are done, this material The necessary decomposition temperature of material is relatively low, less than ferroelectric material, is preferably controlled in less than 500 degree), in the present embodiment, leg adopts plastic sheet Make, Top electrode is prepared in the lower surface of roof.Top electrode can be by gold such as the metal spraying on the roof of surfacing, spray silver Category, or prepared with the metal such as gold, silver in sol evenning machine spin coating, or can also with other methods preparation Top electrodes.In reality In preparation process, the Top electrode of arbitrary shape, arbitrary dimension, any number can be prepared as needed.
Step 2) prepare container
As shown in figure 1, leg is covered and bonds on substrate, obtain by AB glue, 502 glue etc. from surrounding and top Laminar container, the length and width of container are all much larger than thickness.Its purpose is to constitute " flake ".Since if too thick, illumination The just comparison of produced Carrier recombination is more, and the photoelectric current for obtaining is just smaller.Such as long and width is all 1cm, and thickness is 1mm.Container can also be processed by other methods.
Step 3) prepare ferroelectricity liquid
1st step：To prepare BaTiO3(BTO) as a example by ferroelectricity liquid.Can also be that other have ferroelectric microgranule, example Such as lead titanates, bismuth ferrite etc..It is to prepare ferroelectricity BTO nanoparticle first：The method for preparing nanoparticle is a lot, such as molten Glue-gel method, chemical coprecipitation, solid reaction process etc..We are prepared with solid reaction process Example：
By raw material Ba2O3, and Ti2O3, compare Ba according to atomic molar：Ti=1：1 ratio and the purity of raw material calculate each original The required quality of material, being fully ground makes its uniform mixing.Then put the powder in the crucible for cleaning up and be placed in horse Not in stove, in 900 DEG C of first time pre-burning 10h, tentatively into phase.Products therefrom calcines 30h at 1100 DEG C Jing after being fully ground, and makes original Material reacts completely.Third time is carried out again to be fully ground, and obtains BTO nanoparticles.
Followed by prepare BTO ferroelectricity liquid：The BTO nanoparticles of certain mass are uniformly dispersed in certain density In silicone oil.Silicone oil has the features such as high-low temperature resistant, chemical stability are good, steam is forced down, viscosity temperature influence is little, is ferroelectricity The preferable carrier fluid of liquid.But, the characteristic of silicone oil water and oil repellence causes for ferroelectricity BTO microgranule to be dispersed in table therein Face activating agent must have oleophylic performance, and energy coated magnetic microgranule, the phenomenons such as reunion, sedimentation otherwise easily occur.Using Oleic acid As surfactant.
Specially：As requested, it is 5% for example to need to configure volume fraction, BTO ferroelectricity liquid of the volume for 100ml, So, required BTO microgranules volume is 5ml, and its density is about 6g/cm3, then the quality for needing BTO is 30g；The concentration of Oleic acid is 2%, then need to measure the Oleic acid of 2ml；The volume of silicone oil is 100-5-2=93ml；Therefore,
First, weigh BTO nanoparticles (the volume about 5cm of 30g3), in adding the Oleic acid of 2ml, shaken, Ran Houjun Even is dispersed in 93ml silicone oil, puts in the vial or other containers of good seal, shaken on shaking table about 1 it is little When.Then it is 5% just to obtain volume fraction, BTO ferroelectricity liquid of the volume for 100ml.
2nd step：The BTO ferroelectricity liquid syringes obtained in previous step or other methods are injected in container, Ferroelectricity liquid in Fig. 2 is obtained just.
Step 4) prepare nano chain solaode
1st step：The formation of nano chain：Ferroelectricity liquid to obtaining in previous step applies electric field, along direction of an electric field just Obtain ferroelectricity nano chain.In this patent, upper/lower electrode is all conductive, as long as applying electric field to upper/lower electrode, is entirely being held Just there is the presence of electric field in device, be approximately the parallel electric field of capacitor generation.There is the presence of electric field in container, under electric field action Can just move with ferroelectric nanoparticle, form nano chain, naturally it is also possible to apply electric field in addition in external container.For example Vertically apply electric field, just obtain the ferroelectric nano chain of vertical direction shown in Fig. 3.
2nd step：Be put into high-temperature baking by structure is obtained in previous step, it is therefore an objective to which the substance decomposition of the roof of leg is fallen. Different materials can be selected as needed to decide whether to decompose as the material of leg side wall, concrete condition is as follows：If Need the pattern of nano chain to be measured from side, then need to fall sidewall decomposition, otherwise bad observation.Measurement surface pattern when Wait, if Sidewall Height is more than the height of Top electrode, so that when bad observation surface topography, it is necessary to by sidewall decomposition Fall.If measure vertical direction nano chain property, such as electric conductivity, ferroelectricity etc., at this moment side wall do not result in shadow Ring, then can be without removing.The last solar battery structure being made up of ferroelectric nano chain for just obtaining Fig. 4.
After nano chain is formed, due to reuniting, cluster-shaped, rather than one one piece point between nano chain, are readily formed Open, the factor such as reunion degree and the concentration of microgranule, the size for applying electric field and time is relevant, indulging as shown in Fig. 3, Fig. 4 To nano chain, from apply electric field from the beginning of, nano chain just can contact with upper/lower electrode, holding electric field under by liquid evaporation it Afterwards, nano chain substantially can also keep original shape, keep contacting with upper/lower electrode.
Obtained solaode is detected, it is as a result as follows：
As can be known from Fig. 5, the BTO powder prepared by us is substantially spherically-shaped, average to be directly about 20nm.Can from Fig. 6 Know, the I-V curve obtained under positive back bias voltage is asymmetric, this is different mainly due to upper/lower electrode, cause BFO and upper/lower electrode it Between formed barrier height difference caused by.
Furthermore, it is possible to find that the solaode that we obtain has under obvious photovoltaic effect, i.e. illumination and not illumination, The electric current obtained under identical voltage has obvious difference.Our sample of surface has obvious photovoltaic performance.
The present invention is not limited solely to above-described embodiment, in actual fabrication process, it is also possible to turn 90 degrees device, then The electric field of applying level, the nano chain that Mr. is open into.After high-temperature baking, after liquid evaporation, due to action of gravity, nanometer Chain can deposit to bottom, after consolidating, device be gone to original position then, that is, the vertical direction nano chain for obtaining.
In the present embodiment, Top electrode on the roof of leg, can not also be prepared, directly in nano chain during last Upper grown Top electrode.
The present invention is not limited solely to above-described embodiment, if generating horizontal nano chain, after high-temperature baking, liquid After evaporation, due to action of gravity, nano chain can deposit to bottom.This when electrode and nano chain between can produce big section Space.Therefore, if generating horizontal nano chain, Top electrode on the roof of leg, need not be prepared, during last Directly Top electrode is grown in horizontal nano chain, to ensure Top electrode contact nanometer chain.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate technical scheme, although logical Cross above preferred embodiment to be described in detail the present invention, it is to be understood by those skilled in the art that can be Various changes are made to which in form and in details, without departing from claims of the present invention limited range.
