Organic–inorganic halide perovskites have demonstrated significant light detection
potential, with a performance comparable to that of commercially available photodetectors.
In this study, a general design guideline, which is applicable to both inverted and regular
structures, is proposed for high‐performance perovskite photodiodes through an interfacial
built‐in electric field (E) for efficient carrier separation and transport. The interfacial E
generated at the interface between the active and charge transport layers far from the …

… High‐Performance Perovskite Photodiodes In article number 2101729, Dan Wu, Kai
Wang, Aung Ko Ko Kyaw and co‐workers provide a general design guideline for high‐performance
perovskite photodiodes through an interfacial electric field for efficient carrier separation
and transport. The interfacial electric field can be modulated by unintentional doping of the
perovskite, whose doping type and density can be controlled by the annealing time and
temperature. …
