[0020] The preparation process is as follows:
[0021] 1. Extract titanium dioxide from tetrabutyl titanate;
[0022] 2. Prepare the photoanode slurry by grinding the extracted titanium dioxide, ethyl cellulose and terpineol in a ratio of 2:1:7;
[0023] 3. At the same time, mix the extracted titanium dioxide with large particles of 0.2-0.4um in a ratio of 8:1, and grind to prepare a large particle scattering layer with a mass fraction of 15%;
[0024] 4. Apply the slurry prepared in step 2 to the battery and dry it at 120°C;
[0025] 5. After finishing the drying process, use the slurry prepared in step 3 to scrape again, and then continue to sinter at 450°C to obtain a battery photoanode with a large particle coating;
[0026] 6. The photocathode, electrolyte and dyes are purchased finished products;
[0027] 7. Encapsulate the battery under the conditions of 0.4MPa and 120°C.

Abstract
The invention relates to an efficient method for preparing a solar cell. The efficient method for preparing the solar cell comprises the following steps: step 1, titanium dioxide is extracted from a titanium source; step 2, the titanium dioxide extracted in the step 1, ethyl cellulose and terpineol are used for preparing photoanode slurry, wherein the mass ratio of the titanium dioxide to the ethyl cellulose to the terpineol is 2:1:7; step 3, the titanium dioxide extracted in the step 1 and large particletitanium dioxidepowder bodies are mixed and ground to prepare large particle scattering layer slurry, wherein the mass ratio of the titanium dioxide to the large particle titanium dioxide powder bodies ranges from 8:1 to 9:1, and the diameters of the large particle titanium dioxide powder bodies range from 0.2-0.4 um; step 4, the photoanode slurry prepared in the step 2 is used for blade-coating the cell and is dried at 120 DEG C to form a photoanode film; step 5, the large particle scattering layer slurry prepared in the step 3 is used for blade-coating the cell again and then is sintered at 450 DEG C to obtain a cell photoanode provided with a large particle scattering layer; step 6, the cell photoanode obtained in the step 5, existing off-the-shelf photocathodes, an electrolyte and dye are encapsulated into the cell under 0.4 MPa at 120 DEG C.
Description
technical field [0001] The invention relates to a high-efficiency solar cell preparation method, in particular to a dye-sensitized solar cell preparation method for improving cell efficiency by improving the preparation of photoanodes. Background technique [0002] Dye-sensitized solar cells mainly include four parts: photoanode, photocathode, dye and electrolyte. Although the preparation methods of photocathode, dye and electrolyte also have a great influence on the efficiency of the cell, the conversion efficiency of the dye-sensitized cell is to a large extent depends on the preparation of the photoanode slurry. [0003] In order to maximize the effect of the prepared slurry and improve the utilization rate of the light source, for the self-made titanium dioxide powder, we not only use it as a photoanode, but also make it with large particles of titanium dioxide powder solid mixture, to prepare a large particle scattering layer, so as to achieve the purpose of improving ...
