Abstract: A photoelectric conversion device includes a first electrode and a second electrode facing each other, an organic photoelectric conversion layer between the first electrode and the second electrode, and a charge auxiliary layer between the first electrode and the organic photoelectric conversion layer. The organic photoelectric conversion layer is configured to absorb light in at least a portion of a wavelength spectrum of incident light and to convert the absorbed light into an electrical signal. The charge auxiliary layer includes a metal and an oxide. The oxide may be an oxide material that excludes silicon oxide such that the charge auxiliary layer does not include silicon oxide.

Abstract: An image sensor may include a first photo-sensing device on a semiconductor substrate and configured to sense light of a first wavelength spectrum, and second and third photo-sensing devices integrated in the semiconductor substrate and configured to sense light of a second and third wavelength spectrum, respectively. The first photo-sensing device may overlap each of the second and third photo-sensing devices in a thickness direction of the semiconductor substrate. The second and third photo-sensing devices do not overlap in the thickness direction and each have an upper surface, a lower surface, and a doped region therebetween. The third photo-sensing device includes an upper surface deeper further from the upper surface of the semiconductor substrate than the upper surface of the second photo-sensing device and a doped region thicker than the doped region of the second photo-sensing device. The image sensor may omit the first photo-sensing device.
