All-Perovskite Photodetector with Fast Response
Perovskites have attracted substantial attention on account of their excellent physical properties and simple preparation process. Here we demonstrated an improved photodetector based on solution-processing organic-inorganic hybrid perovskite CH 3 NH 3 PbI 3− x Cl x layer decorated with CsPbBr 3 per...
