A Perovskite‐Based Photodetector with Enhanced Light Absorption, Heat Dissipation, and Humidity Stability

The manipulation of microstructure from the growth stage is desired in perovskite materials to improve the environmental stability and enhance the perovskite‐based device performance. Herein, the traditional challenges of self‐assembly of multifunctional perovskite nano/microwires (MWs) are overcome...
