| titleOfInvention | Based on PbBr2Microporous regulated fully inorganic CsPbBr3Perovskite solar cell and preparation method and application thereof |
| abstract | The invention provides a method based on PbBr 2 Microporous regulated fully inorganic CsPbBr 3 A perovskite solar cell and a preparation method and application thereof are disclosed, and concretely, an electron transmission layer is prepared by spin-coating a quantum dot solution on a conductive film substrate, and then the electron transmission layer is heated and spin-coated with PbBr 2 Solution annealing to form PbBr 2 A porous film is coated with CsBr solution by spin coating for multiple times to prepare CsPbBr 3 A perovskite thin film. By changing PbBr 2 Crystallization temperature control of PbBr 2 Porosity in the film to allow rapid diffusion of CsBr to PbBr 2 Preparation of large-grain CsPbBr inside thin film 3 A film. PbBr 2 The microporous structure of the film is large-grain CsPbBr 3 Provides space for reducing the residual compressive stress of the perovskite grains. The invention provides an all-inorganic CsPbBr 3 The maximum crystal grain of the film can reach 1.62 microns, and the solar cell assembled by the film has good stability and high photoelectric conversion rate, and has important practical value and economic value for promoting the industrialization process of the perovskite solar cell. |
