METHOD OF MANUFACTURING PEROVSKITE THIN FILM CONTAINING TIN AND PHOTOELECTRIC DEVICE HAVING THE PEROVSKITE THIN FILM

摘要

A method for manufacturing a perovskite thin film is disclosed. The method of manufacturing a perovskite thin film is the step of forming a metal (+ divalent) chalcogenide thin film on a substrate, and applying a precursor solution of the following formula 1 or formula 2 on the metal (+ divalent) chalcogenide thin film And forming a preliminary thin film, and converting the preliminary thin film into a perovskite thin film having a composition of the following formula (3) by heat treatment. [Formula 1] [Formula 2] [Formula 3] In Formulas 1 to 3, A represents a +1 valent organic cation or a +1 valent metal cation, M ¹ represents the first metal, M ¹ and M ² each represent different +divalent metal cation, X represents a halogen anion, and x may be a real number greater than 0 and 1 or less.
