Halide perovskites in wide‐spectrum photodetection
Bulletin of the Korean Chemical Society, EarlyView.Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.
