Method of fabricating metal halide perovskite nanocrystal particle layer and optoelectronic device using the same

摘要

A method for manufacturing a metal halide perovskite nanocrystal particle thin film and a photoelectric device using the same are provided. A method for manufacturing a metal halide perovskite nanocrystalline particle thin film comprises: preparing an organic solution containing metal halide perovskite nanocrystalline particles dispersed in an organic solvent; applying the organic solution on the substrate to form a perovskite Forming a nanocrystalline grain thin film, and drying the formed nanocrystalline grain thin film through air jet. Accordingly, the metal halide perovskite nanocrystalline particles can be manufactured in a short time, such as bar coating, and can be manufactured by a roll-to-roll method and a printing method suitable for a large area.
