    Abstract: An image sensor includes a color filter array, a first photoelectric conversion device configured to absorb first light passing through the color filter array and convert the absorbed first light into electrical signals, and a second photoelectric conversion device configured to absorb second light passing through both the color filter array and the first photoelectric conversion device and convert the absorbed second light into electrical signals. The first photoelectric conversion device includes a first photoelectric conversion layer configured to selectively absorb a mixed light of the first and second colors. The second photoelectric conversion device comprises a second photoelectric conversion layer configured to absorb light including a third color. Each of the first to third colors is one of three primary colors. The image sensor combines the electrical signals converted from the first and second photoelectric conversion devices to obtain electrical signals of the first to third colors.

    Abstract: An organic image sensor may be configured to obtain a color signal associated with a particular wavelength spectrum of light absorbed by the organic image sensor may omit a color filter. The organic image sensor may include an organic photoelectric conversion layer including a first material and a second material. The first material may absorb a first wavelength spectrum of light, and the second material may absorb a second wavelength spectrum of light. The organic photoelectric conversion layer may include stacked upper and lower layers, and the respective material compositions of the lower and upper layers may be first and second mixtures of the first and second materials. A ratio of the first material to the second material in the first mixture may be greater than 1/1, and a ratio of the first material to the second material in the second mixture may be less than 1/1.
