| titleOfInvention | A method for preparing high crystallinity perovskite and product application thereof |
| abstract | The invention discloses a method for preparing high crystallinity perovskite and its product application, comprising the following steps: (1) preparing a 4 main group metal halide salt solution and a halogenated organic salt solution; (2) preparing a halogenated organic salt-organic A mixed solution of cations; (3) a mixed solution of metal halide salt-inhibitor-additive is prepared; (4) the mixed solution of halogenated organic salt-organic cation in step (2) and the metal halide salt in step (3) After the mixed solution of the inhibitor-additive is evenly mixed, it is allowed to stand for aging to obtain a two-dimensional/quasi-two-dimensional layered perovskite solution; (5) the two-dimensional/quasi-two-dimensional layered perovskite in step (4) is mixed The mineral solution is prepared on the substrate by the coating method, and after annealing treatment, the perovskite is obtained. The invention regulates the crystal crystallization rate by intervening a crystallization inhibitor, improves the matching degree of the speed of A-site ion transport and assembly and the perovskite crystallization rate, thereby reduces the disorder of the crystal structure and improves the crystallinity of the perovskite. |
