WebMar 20, 2024 · The main way to expand the spectral response range of PSCs is to prepare a broad-spectrum perovskite. At present, the absorption range of most perovskites is only between 300 and 800 nm, and most of the sunlight is still not effectively used, and the insufficient use of ultraviolet light and NIR light are basically all wasted. WebJul 4, 2024 · Notably, this UV photodetector demonstrates a high detectivity of 1.22 × 1012 Jones, outperforming some traditional wide‐bandgap UV detectors. The wavelength‐dependent photoresponsivity measurement allows the direct observation of an admirable cut‐off wavelength at 360 nm, which indicates a superior spectral selectivity. locksmith howell michigan
