Photo-processing of perovskites: current research status and challenges

Abstract

Photo-processing has been established as a powerful technique for the synthesis and structure modification of perovskites. In this review, the authors discuss the mechanisms of photo-processing of perovskites and summarize the recent progress in the photo-processing of perovskites for synthesis, patterning, ion exchange, phase transition, assembly, and ion migration and redistribution. The applications of photo-processed perovskites in photovoltaic devices, lasers, photodetectors, light-emitting diodes (LEDs)
