Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, and in particular relates to a structure of a perovskite solar cell. Background technique [0002] With the increasing shortage of traditional fossil energy, people pay more and more attention to the research of renewable energy, especially solar cells. Traditional crystalline silicon solar cells are relatively expensive, complex in process, and have strict requirements on production equipment, while the new generation of dye-sensitized cells and organic solar cells are too inefficient and have poor stability. Perovskite solar cells have the advantages of high photoelectric conversion efficiency and extensive industrialization. [0003] At present, in the existing technologies for perovskite solar cells, perovskite solar cells are usually made of expensive metals such as Au and Ag as electrode materials. However, under the action of water vapor, perovskite solar cell devices and ...
