Abstract

The invention belongs to the technical field of renewable clean energy source, and specifically relates to a preparation method of a dye-sensitized solar battery counter electrode material. In the method, emulsifier OP-10, liquid paraffin and other materials are used as raw materials to obtain oil-in-water emulsion, the oil-in-water emulsion is mixed with sodium metasilicate nonahydrate solution for reaction, thus, counter electrode sizing agent is obtained, the counter electrode sizing agent is subjected to refrigerated centrifugation and precipitate is collected, the precipitate is mixed with dispersed gelatinous coating and sprayed on a FTO conducting glass surface, thus, the dye-sensitized solar battery counter electrode material is obtained. According to the method provided by the invention, an outer hole of an organic dispersed carbon nano tube is plugged by tungsten carbide, electrocatalytic efficiency of the counter electrode is improved, the surface of the carbon nano tube ismodified by paranitroaniline diazo salt, convective heat loss of the electrode material is reduced, photoelectric conversion energy storage is also facilitated, titanium dioxide added in the coating plays a role in a flatting effect and a function of increasing specific area of the surface, photoelectric conversion efficiency of the electrode material is improved, thus, the method has wide application foreground.

Description

technical field [0001] The invention belongs to the technical field of green renewable clean energy preparation, and in particular relates to a preparation method of a dye-sensitized solar cell counter electrode material. Background technique [0002] With the rapid development of society, human's demand for energy is increasing day by day. However, the energy crisis and environmental pollution caused by excessive exploitation and use of fossil energy have gradually emerged, and have become the primary factors restricting the sustainable and healthy development of economy and society. factor. Therefore, the development of renewable energy is one of the effective ways to solve the above problems. As an inexhaustible, pollution-free and clean natural green energy, solar energy has become one of the most promising energy sources. [0003] Dye-sensitized solar cells are a new type of solar cells. Compared with traditional silicon solar cells, they have many advantages such as ...
