Recent progress in organometal halide perovskite photodetectors

Organometal halide perovskite photodetectors have recently received significant attentions because of their excellent photoelectrical performance. Perovskite photodetectors can be mainly categorized into two types: photovoltaic photodetectors in vertical structure and photoconductive photodetectors in lateral structure. Herein, we review the progress in organometal halide perovskite photodetectors for the past few years, focusing on their key figure-of-merit features and operation mechanisms of different device structures.
