Abstract

The invention relates to a method for preparing a titanium dioxide photo-anode of a DSSC (Dye-Sensitized Solar Cell). The method comprises the steps of immersing cleaned conductive glass into a titanium tetrachloride solution, taking out the conductive glass after being subjected to heat preservation in 25-75 DEG C for 10-90 minutes, leaching and drying the conductive glass, and obtaining the conductive glass which is subjected to once titanium tetrachloride processing, wherein the concentration of the titanium tetrachloride solution is 20-500 mM, and solvents in the titanium tetrachloride solution are water and / or alcohol; drying the obtained conductive glass after coating a titanium dioxide sizing agent on the surface of the obtained conductive glass which is subjected to the once titanium tetrachloride processing, carrying out single sintering by baking the conductive glass in 250-650 DEG C for 0.1-5 hours, and obtaining the titanium dioxide photo-anode of the DSSC. According to the method disclosed by the invention, twice titanium tetrachloride processing in a standard method is reduced into the once titanium tetrachloride processing, not only is the production technology simplified and is the production cost reduced, but also the emission load of the corrosive titanium tetrachloride solution in a production process is reduced, and thus the production process is more environment-friendly.

Description

technical field [0001] The invention relates to the field of dye-sensitized solar cell materials, in particular to a method for preparing a titanium dioxide photoanode. Background technique [0002] In 1991, Swiss Lausanne Advanced Technology (EPFL) et al, using bipyridyl ruthenium (II) complex dyes and nanoporous TiO2 thin-film dye-sensitized nano-thin film solar cells, obtained a photoelectric conversion efficiency of 7.1%. This breakthrough has opened up a new world for the study of dye-sensitized nano-thin film solar cells, especially providing new ideas for future industrial production. Compared with the expensive production cost and complicated preparation process of silicon solar cells that currently dominate the market, the most attractive features of this cell are its cheap raw materials and relatively simple manufacturing process, and its stable performance and low attenuation. It has great application prospect. [0003] However, this photoelectric conversion t...
