Miniaturized Self‐Powered Perovskite Spectrometer (Small 37/2026)
Miniaturized Spectrometers Miniaturized reconstructive spectrometers with small footprints and light weight have attracted much attention. In Research Article e12206, Nan Zhang, Yunxia Hu, Lingling Huang, Jing Wei, and co-workers report a miniaturized, high-performance spectrometer composed of self-powered perovskite photodetectors with gradient bandgaps. This perovskite spectrometer achieves a high-resolution spectrum using only 8 photodetectors by integrating the compressive sensing algorithm, which paves the way for the development of low-cost, integrated, low-power and chip-based devices.
