| titleOfInvention | An in situ generation of water, thermally stable passivation layer and perovskite solar cells with passivation layer |
| abstract | The invention discloses an in-situ generation of water with self-limiting effect, thermally stable passivation layer of lead halide-based organic-inorganic hybrid material and preparation of perovskite solar cells with passivation layer. The introduction of corresponding organic salt ligands on the surface of perovskite reacts in situ with lead iodide in perovskite to form a layer of dense water and thermally stable passivation layer material; this reaction can be applied to the formal application of perovskite solar cells at the same time. In the and trans structure, it has a wide range of applications and has a self-limiting effect; and the organic molecules of the lead halide-based organic-inorganic hybrid material and the inorganic network pass chemical bonds, such as covalent bonds, hydrogen bonds, ionic bonds, etc., making hybrid coordination The material is compounded at the "molecular level", and the advantages of the two components are fused at the molecular level. It has excellent passivation defect effect, reduces non-radiative recombination, and the device can exhibit higher open circuit voltage and fill factor, so it has more High photoelectric conversion efficiency; and the lead halide-based organic-inorganic hybrid passivation layer material can significantly improve the wet-heat stability of perovskite due to its excellent intrinsic water and thermal stability. This scheme is conducive to opening up a new idea of passivation materials and accelerating the commercialization of perovskites. |
