Progress on the research of all-inorganic perovskite CsPbX3

Abstract

Abstract All inorganic lead halide perovskite CsPbX3 (X = CI, Br, I) has excellent optical properties such as narrowband luminescence with high efficiency, adjustable optical band gap, large absorption cross-section and high carrier transmission rate, which pays an important role in photoelectric fields such as solar cells, photoelectric and etc. Starting from the crystal structure of perovskite, this paper firstly introduces its synthesis method and morphology control method; following by the emphasizing description on its size effect, photocatalytic properties and influencing factors of optical properties; then this study discusses the issues regarding its stability; and finally summarizes and prospects its application and future development, so as to offer some references for future studies.
