    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.

    Abstract: An image sensor may include a photoelectric device configured to selectively absorb light associated with a first color of three primary colors, a semiconductor substrate that is stacked with the photoelectric device and includes first and second photo-sensing devices configured to sense light associated with second and third colors of three primary colors. The first and second photo-sensing devices may have different thicknesses, different depths from a surface of the semiconductor substrate, or different thicknesses and different depths from the surface of the semiconductor substrate. At least one part of a thickness area of the first photo-sensing device may overlap at least one part of a thickness area of the second photo-sensing device in a parallel direction extending substantially parallel to the surface of the semiconductor substrate.

    Abstract: An electronic device may include at least one image sensor that includes a plurality of photo-sensing devices, a photoelectric device on one side of the semiconductor substrate and configured to selectively sense first visible light, and a plurality of color filters on separate photo-sensing devices. The plurality of color filters may include a first color filter configured to selectively transmit a second visible light that is different from the first visible light and a second color filter transmitting first mixed light including the second visible light. The electronic device may include multiple arrays of color filters. The electronic device may include different photoelectric devices on the separate arrays of color filters. The different photoelectric devices may be configured to sense different wavelength spectra of light.

    Abstract: An image sensor includes a semiconductor substrate integrated with at least one of a first photo-sensing device that may sense a first wavelength spectrum of visible light and a second photo-sensing device that may sense second wavelength spectrum of visible light, and a third photo-sensing device on the semiconductor substrate that may selectively sense third wavelength spectrum of visible light in a longer wavelength spectrum of visible light than the first wavelength spectrum of visible light and the second wavelength spectrum of visible light. The first photo-sensing device and the second photo-sensing device may overlap with each other in a thickness direction of the semiconductor substrate.
