High‐Performance Perovskite–Graphene Hybrid Photodetector

Abstract

A high-performance novel photodetector is demonstrated, which consists of graphene and CH3 NH3PbI3 perovskite layers. The resulting hybrid photodetector exhibits a dramatically enhanced photo responsivity (180 A/W) and effective quantum efficiency (5× 104%) over a broad bandwidth within the UV and visible ranges.
