| titleOfInvention | A method for preparing high crystallinity perovskite thin films in air |
| abstract | The invention relates to a method for preparing a high-crystallinity perovskite film in air, comprising: dissolving lead halide in N,N-dimethylformamide to obtain lead halide/N,N-dimethylformamide solution; dissolve methylamine halide in isopropanol to obtain methylamine halide/isopropanol solution; spin-coat lead halide/N,N‑dimethylformamide solution onto a conductive substrate and anneal at 60‑80 °C for 10 ‑20 minutes to get the lead halide film, put it on the heating platform, quickly cover the sample with a petri dish, then drop dimethyl sulfoxide on the edge of the petri dish, treat at 60‑80 °C for 10‑20 minutes, spin coating Methylamine halide/isopropanol solution, quickly cover the sample with a Petri dish, anneal at 90-110°C for 10-20 minutes, and obtain it. The method of the invention effectively improves the flatness of the surface of the perovskite film, effectively guarantees the perovskite film, significantly improves the repeatability of devices, and reduces the preparation cost of the perovskite film. |
