Perovskites with tunable bandgap have emerged as a class of promising materials to detect photons spanning from ionizing radiation to infrared spectral range. While perovskites with different dimensionalities have been developed for photodetection at different wavelengths, upscaling, stability, and integration of perovskite photoactive layers with readout integrated circuits remain major technical hurdles to be surmounted before the materials can be put into production.

In this collection at Nature Communications, Communications Materials, Communications Engineering, and Scientific Reports, we aim to bring together cutting-edge direct perovskite photodetectors, indirect perovskite scintillators, and advanced applications for imaging and computing crossing multidisciplinary areas, and to invite commentaries from experts. Topics of interest include but are not limited to the following:
