Title: SEQUENTIAL PROCESSING WITH VAPOR TREATMENT OF THIN FILMS OF ORGANIC-INORGANIC PEROVSKITE MATERIALS
Abstract:
According to some embodiments of the present invention, a method of producing an organic-inorganic perovskite thin film includes depositing a layer of inorganic material on a substrate to form an inorganic film, and performing an organic vapor treatment of the inorganic film to produce an organic-inorganic perovskite thin film. The layer of inorganic material comprises an inorganic anion layer having a metal-ligand framework, and the organic vapor treatment provides organic cations capable of becoming inserted into the metal-ligand framework of the inorganic anion layer to form a perovskite structure.
