Abstract
A photoelectric device includes a first electrode and a second electrode facing each other and a photoelectric conversion layer between the first electrode and the second electrode and configured to convert light in a particular wavelength spectrum of light of a visible wavelength spectrum of light into an electric signal. The photoelectric conversion layer may include a p-type semiconductor configured to selectively absorb light in a first wavelength spectrum and an n-type semiconductor having a peak absorption wavelength in a second wavelength spectrum of greater than or equal to about 750 nm, an image sensor. The photoelectric conversion layer may include a first semiconductor of an absorption spectrum of a first peak absorption wavelength, and a second semiconductor of an absorption spectrum of a second peak absorption wavelength that is longer than the first peak absorption wavelength by at least about 100 nm.
