Abstract

Photoinduced halide segregation in mixed halide hybrid perovskites [i.e., APb(I1–xBrx)3] represents an intrinsic instability that impedes their commercialization. Resolving this issue requires deve...

Abstract

Mixing bromine and iodine within lead halide perovskites is a common strategy to tune their optical properties. This comes at the cost of instability, as illumination induces halide segregation and degrades device performances. Hence, understanding the behavior of mixed-halide perovskites is crucial for applications. In 3D perovskites such as MAPb(Br
