Description

[0001] 【Technical field】 [0002] The invention relates to a solar cell, in particular to a composite thin-film dye-sensitized solar cell and a manufacturing method thereof. [0003] 【Background technique】 [0004] Dye-sensitized solar cells are a new type of solar cells. Compared with traditional silicon solar cells, they have become a new type of solar cells due to their advantages such as wide source of raw materials, low cost, and high theoretical conversion efficiency. [0005] Nanoporous oxide films as the semiconductor layer are the core part of dye-sensitized solar cells. The thin film material is coated on the conductive glass to form the anode of the battery, the dye absorbs sunlight, generates electronic transitions, and the electrons are transferred to the thin film material, and finally exported to form an electric current by the external circuit. In related technologies, thin film materials mainly focus on TiO 2 The research also includes other semiconductor oxi...
