Description

technical field [0001] The invention relates to the technical field of dye-sensitized solar cells, in particular to a three-layer TiO 2 Composite thin-film dye cells. Background technique [0002] With the development of solar technology, how to construct efficient solar cells is the core issue in the process of solar energy development. Among many solar cells, compared with traditional solar cells, dye-sensitized solar cells have the advantages of simple preparation process, high conversion efficiency, low cost, and no pollution. However, the current dye-sensitized solar cells still cannot meet the requirements of industrialization. TiO 2 As the core part of DSSC, the photoanode is the key to determine the photoelectric conversion efficiency. Therefore, a variety of preparation techniques and methods such as doping and compounding are used to improve the TiO 2 The effective use of sunlight by photoanodes and the improvement of photoelectric conversion efficiency are the...
