Abstract

Abstract: Compared with organic–inorganic hybrid perovskites, fully inorganic perovskites show an increased stability and are therefore attracting considerable attention, especially in recent years. Such materials are not only being extensively used in applications such as solar cells and light-emitting diodes, but also show great potential as photodetectors due to their exceptional optoelectronic properties. In this review, the recent progress on emerging photodetectors based on inorganic perovskites is comprehensively summarized, focusing on the versatile compositions and morphologies of constituent materials and diverse device architectures, and covering the sensing regions from UV–visible–NIR to x-ray and even gamma-ray. A brief outlook that highlights the current challenges impeding the commercialization of inorganic perovskite-based photodetectors is also included, and possible solutions to these problems are provided.
