Abstract

Abstract : Photodetectors are designed, which operate in the broadband regime upon bottom illumination (from the indium tin oxide (ITO) side) and in the narrowband regime upon top illumination (from the air/perovskite side). The narrowband photodetectors show high external quantum efficiency of above 10 4 %. The operational spectrum of the photodetectors can also be tuned by adjusting the halide composition in the active material.
