Abstract

Abstract : Blue Photodetectors Vertically stacked blue/green/red photodetectors receive great attention for next‐generation image sensors, where a high‐performance blue device is the most important building block. In article 2206932, Gill Sang Han, Hyun Suk Jung, Sangwook Lee, and co‐workers demonstrate a high‐performance self‐powered blue photodetector based on wide‐bandgap halide perovskites. Outstanding external quantum efficiency (84.9%) and responsivity (0.307 A W −1 ) with improved stability is achieved by compositional engineering.
