Metal Doped Lead Halide Perovskites: Synthesis, Properties

The instability of halide perovskite based devices is mainly due to the intrinsic phase transition and poor quality of the perovskite active layers For example, despite perovskite FAPbI 3 with a lower band gap 1 48 eV having an extended light absorption range compared to MA based or Cs based perovskite, the black perovskite phase α FAPbI 3
