Abstract

The invention relates to a dye sensitized solar cell photoanode, a cell and a manufacturing method of the photoanode. The dye sensitized solar cell photoanode comprises a Ti substrate, a TiO2 nano grid layer and a TiO2 nanotube array, wherein the TiO2 nano grid layer is positioned on the Ti substrate; nanotubes of the TiO2 nanotube array respectively grow on the Ti substrate and pass through the TiO2 nano grid layer. According to the dye sensitized solar cell photoanode, the cell and the manufacturing method of the photoanode, the adsorption capability of TiO2 to dye is improved, and thus the performance of the dye sensitized solar cell photoanode is improved; in addition, electrons can be captured by the TiO2 nanotubes, and the electron transmission rate is increased.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a dye-sensitized solar cell photoanode, a battery and a preparation method of the dye-sensitized solar cell photoanode. Background technique [0002] Dye-sensitized solar cells are the third generation of thin-film solar cells. Its main part is TiO with high specific surface area 2 film, dyes that can chemisorb and have a strong absorption coefficient for sunlight and penetrate the TiO 2 Thin film and electrolyte matched to the redox potential of the dye. However, current dye-sensitized solar cells suffer from low electron transport rates. Contents of the invention [0003] The problem solved by the invention is the problem of low electron transport rate of existing dye-sensitized solar cells. [0004] In order to solve the above problems, the present invention provides a dye-sensitized solar photoanode, which includes a Ti substrate, TiO 2 Nanogrid layer and TiO 2 na...
