Demonstrates high-resolution spectra in miniaturized spectrometers, highlighting efficiency for low-cost devices.
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.
