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 10⁴ %. The operational spectrum of the photodetectors can also be tuned by adjusting the halide composition in the active material.

Keywords: broadband; narrowband; perovskites; photodetectors.
