PREPARING METHOD OF LARGE-AREA PEROVSKITE THIN FILM

摘要

The present disclosure relates to a preparing method of a large-area perovskite thin film, comprising: forming an organic metal halide-alkylamine compound by exposing an organic metal halide compound having a perovskite structure to an alkylamine gas; preparing a coating solution by adding a solvent on the organic metal halide-alkylamine compound; and preparing a perovskite thin film by coating the coating solution on a substrate.
