Abstract

Read online

The high dark current of perovskite photodetectors hinders the full potential of perovskites as active material for X-ray detectors. Here, Jin et al. provide a strategy to reduce the dark current to zero and massively enhance the signal-to-noise ratio of perovskite X-ray detectors and photodetectors.
