Abstract

The invention discloses a preparation method of a flexible, hybridized and dye sensitized solar cell. The preparation method includes the steps of sensitizing two layers of a TiO2 photoanode respectively by two dyes with different spectral response ranges to obtain a flexible and hybridized photoanode; packaging the hybridized photoanode together with an electrode together and filling with electrolyte to obtain the flexible, hybridized and dye sensitized solar cell. The method in the invention improves the spectral absorption and conversion efficiency of DSCs (Dye Sensitized Solar Cell). The method has advantages of low preparation cost, simple preparation technique and the like. The cells prepared in the method are soft, flexible and light, thereby expanding the application range of solar cells.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a method for preparing a flexible hybrid dye-sensitized solar cell, in particular to a method for preparing a hybrid photoanode of a flexible dye-sensitized solar cell. Background technique [0002] Making full use of solar energy is one of the important ways to solve the energy crisis, so the research and development of solar cells has always attracted much attention. In the current commercial solar cell market, inorganic crystalline silicon solar cells occupy a dominant position. However, due to problems such as high manufacturing cost and complicated processing technology of crystalline silicon, the application of this kind of solar cell is limited. Dye-sensitized solar cells (DSCs) have received extensive attention since Grötzel et al. published the article on nano-thin film dye-sensitized solar cells (DSCs) in 1991. Compared with inorganic crystalline silicon solar c...
