| titleOfInvention | A kind of lead halide perovskite polycrystalline sheet and preparation method thereof |
| abstract | The invention discloses a lead-halide perovskite polycrystalline flake and a preparation method thereof. The method makes the precursor powder fully react through in-situ hot pressing, can achieve 100% utilization rate of raw materials, and avoid the waste of raw materials. The method is heated at the same time of pressurization, which avoids the increase of steps caused by the first pressurization and then the heating; and the method is suitable for preparing lead-halide perovskite polycrystalline flakes, and the precursor reaction raw materials are easy to volatilize. Through the design of the mold, the reaction can be carried out in a closed environment, and the proportion of the reaction products and the thickness of the perovskite film can be precisely controlled; this method synthesizes the perovskite crystal film at low temperature, reduces the production cost, and at the same time The material can be prepared according to the thickness of the target flakes. The polycrystalline flakes obtained by this method have carrier mobility and carrier collection efficiency comparable to single crystal materials, and can be used to prepare high-quality perovskite optoelectronic devices. |
