| titleOfInvention | A method for extracting residual lead iodide from lead halide perovskite materials |
| abstract | The invention discloses a method for extracting residual lead iodide from lead halide perovskite materials, comprising the following steps: coating a lead salt precursor solution on a substrate, annealing and crystallization to form a lead salt film; The precursor solution and the oleylamine salt precursor solution are sequentially coated on the lead salt film to form the perovskite precursor film; the substrate and the perovskite precursor film are annealed and crystallized in the atmospheric environment to form the perovskite Material. The method extracts the residual lead iodide in the lead-halide perovskite material from the grain boundary to the surface of the perovskite grain, reduces the defect state density, and the prepared perovskite material can make the photoelectricity of the perovskite solar photovoltaic device possible. The conversion efficiency is effectively improved, up to 24.28%, and the stability of the perovskite device is significantly improved. |
