Title:
PREPARATION METHOD FOR ORGANIC-INORGANIC HYBRID PEROVSKITE THIN FILM AND PREPARATION METHOD FOR SEMI-TRANSPARENT SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2023/184626
Kind Code:
A1
Abstract:
Disclosed in the present application are a preparation method for an organic-inorganic hybrid perovskite thin film and a preparation method for a semi-transparent solar cell. The preparation method for a perovskite thin film comprises the following steps: dissolving methyl ammonium bromide, lead bromide, lead iodide, formamidine hydriodate and chloromethylamine in a mixed solvent, and uniformly mixing same to obtain a precursor solution; coating a substrate with the precursor solution, then annealing same for 4-6 min at 65-75ºC, and then annealing same for 8-12 min at 145-155ºC, so as to obtain an organic-inorganic hybrid perovskite thin film, wherein the mixed solvent comprises DMF and a first solvent, and the volume ratio of DMF to the first solvent is 8.9-9.1 : 0.9-1.1, with the first solvent comprising N-ethyl-2-pyrrolidone, N-methyl-2-piperidone and N-N-2-methylacetamide.
