Perovskite image sensors take photos with less light, higher resolution, and better color resolution than conventional silicon sensors

"each pixel in silicon image sensor receives around a third of available light, overcome using lead halide perovskite semiconductor stacked pixels utilizing every photon for color recognition... perovskite sensors' hyperspectral imaging control wavelength range absorbed by each layer... perovskite containing slightly more iodine ions absorbs red, add more bromine for green, chlorine more blue, without any need for filters... smartphones, medical analysis, automated environmental/ agricultural monitoring"
