Recent Research Trends for Improving the Stability of Organo/Inorgano Halide Perovskites

Abstract

Because of their superior optical, and electrical properties, lead halide perovskites have emerged as potential materials for light-emitting-diodes. However, some obstacles have yet to be overcome for practical applications including low exciton binding energy, the difficulty of fabricating uniform perovskite films,, and their instability to heat, light, and moisture. In this review, we focus on strategies to improve the lifetime, and stability of perovskites such as core-shell structure, ligand exchange, and doping.
