A tetrachromatic light sensor can detect in four independent color channels and extend its detection range beyond the visible spectrum. However, current sensors face challenges such as inability to work reliably extreme temperatures. In this work, we present a fully integrated tandem perovskite imaging system. Four layers of all-inorganic perovskites device serve ultraviolet, blue, green, red detectors discriminate spectral non-spectral colors. The image comprises 32 × color-selective pixel arrays. non-encapsulated is tested function from 150 500 K under atmospheric pressure vacuum environments. fabrication process structure are scalable, with potential be used for harsh environmental conditions.
