Abstract

Abstract : A highly sensitive photodetector with broadband response by using perovskite as the active layer is reported by Jiang Huang, Junsheng Yu, and co‐workers in article number1800979 . To extend the spectral response range from visible (Vis) to near‐infrared (NIR) wavelengths, an antisolvent additive solution process is demonstrated to dope PbS quantum dots between the grain boundaries of the perovskite. The image shows the perovskite photodetector generating an electrical signal under Vis–NIR light irradiation with the relevant wavelength response.
