Abstract
An image sensor includes a plurality of pixels including a blue pixel, a green pixel, and a red pixel. At least a portion of the plurality of pixels includes a first photo-sensing device including a first perovskite which absorbs at least a portion of light in a visible light wavelength spectrum, and a second photo-sensing device which is stacked with the first photo-sensing device and senses at least a portion of light in an infrared wavelength spectrum.
