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