| titleOfInvention | A kind of preparation method of large-grain perovskite film |
| abstract | The invention relates to a method for preparing a large-grain perovskite film, which uses mixed anion-cation type perovskite as the main system, and adds Pb(SCN) 2 as an additive to regulate the growth of the film. It includes the preparation process of preparing a mixed anion-cation type perovskite precursor solution and adding additives to the film. Through the regulation of Pb(SCN) 2 additives, a flat and dense perovskite film with large-sized grains is obtained. The invention has the advantages of simple process, convenient operation and effective and rapid film formation. By using mixed anion-cation type perovskite as the main system, and using additives to regulate the growth of perovskite film, the growth of large-sized perovskite grains is realized, which not only reduces the internal defects of the film, improves the carrier transport life, but also The defects of the grain boundary are reduced, the environmental stability of the perovskite film is greatly improved, the performance of the perovskite solar cell is enhanced, and the preparation of a high-efficiency, stable and low-hysteresis perovskite film device is realized. |
