| titleOfInvention | A method to improve the stability of perovskite thin films |
| abstract | The invention relates to a method for improving the stability of a perovskite film, comprising the following steps: placing a substrate containing a perovskite film on a surface in a reaction chamber, repeatedly cleaning the reaction chamber with an inert gas; The hydrogen sulfide gas reacts with the molecules of the perovskite film to form a sulfide layer on the surface of the perovskite film; after the reaction is completed, the reaction chamber is repeatedly cleaned with an inert gas, inflated to normal pressure, and the reaction chamber is cooled after Take out the reacted substrate. The invention changes the chemical composition of the surface and the grain boundary of the perovskite material by generating nano-scale lead sulfide layers on the grain boundary and the surface of the perovskite thin film material, suppresses the degradation of the perovskite, thereby improving the perovskite thin film. performance of the material and prolong its stability. |
