Abstract

An image sensor may include a photodiode within a semiconductor substrate and configured to sense light in an infrared wavelength spectrum of light, a photoelectric conversion device on the semiconductor substrate and configured to sense light in a visible wavelength spectrum of light, and a filtering element configured to selectively transmit at least a portion of the infrared wavelength spectrum of light and the visible wavelength spectrum of light. The filtering element may include a plurality of color filters on the photoelectric conversion device. The photoelectric conversion device may include a pair of electrodes facing each other and a photoelectric conversion layer between the pair of electrodes and configured to selectively absorb light in a visible wavelength spectrum of light. The filtering element may be between the semiconductor substrate and the photoelectric conversion device and may selectively absorb the infrared light and selectively transmit the visible light.
