Preparation method of photoanode, photoanode and dye-sensitized solar cell

Abstract

The application provides a method for preparing a photoanode, a photoanode and a dye-sensitized solar cell. The method includes: adding deionized water and dilute hydrochloric acid to the first hydrothermal reaction kettle, and slowly adding titanium isopropoxide dropwise to obtain the second A mixed solution, put the FTO conductive glass into the first mixed solution for hydrothermal reaction, take out the FTO conductive glass after cooling down to room temperature, sinter the dried FTO conductive glass, and cool down to room temperature to obtain the first light Anode, add ethylene glycol solution in the second hydrothermal reaction kettle, and add tetrabutyl titanate in the ethylene glycol solution, and after stirring, add hydrofluoric acid and acetic acid, and stir to obtain the second mixed solution; A photoanode is added to the second mixed solution for hydrothermal reaction, and after cooling to room temperature, the FTO conductive glass taken out is rinsed and dried with deionized water to obtain a second photoanode to solve the problem of electron transmission in existing dye-sensitized solar cells. The technical problem is that the properties and light scattering ability are poor and the specific surface area is not high.

Description

technical field [0001] The present application relates to the field of solar cell manufacturing, in particular to a method for preparing a photoanode, a photoanode and a dye-sensitized solar cell. Background technique [0002] The energy problem is the most important issue restricting the development of the world economy at present. As an inexhaustible, pollution-free and clean natural green energy, solar energy has become one of the most promising energy sources. At present, the most widely researched and applied solar cells are mainly silicon-based solar cells, but the cost of raw materials for silicon-based cells is high, the production process is complicated, and the potential for efficiency improvement is limited. The theoretical limit of its photoelectric conversion efficiency is 30%, which limits its civilian use. , there is an urgent need to develop low-cost solar cells. [0003] 1991 Swiss Scholar et al. published an article in Nature, and proposed a new type of ...
