    Abstract: An organic photoelectronic device includes a first electrode and a second electrode facing each other and a light-absorption layer between the first electrode and the second electrode and including a first region closest to the first electrode, the first region having a first composition ratio (p1/n1) of a p-type semiconductor relative to an n-type semiconductor, a second region closest to the second electrode, the second region having a second composition ratio (p2/n2) of the p-type semiconductor relative to the n-type semiconductor, and a third region between the first region and the second region in a thickness direction, the third region having a third composition ratio (p3/n3) of the p-type semiconductor relative to the n-type semiconductor that is greater or less than the first composition ratio (p1/n1) and the second composition ratio (p2/n2).

    Abstract: A photoelectric device includes a first electrode, a second electrode, a photoelectric conversion layer between the first electrode and the second electrode, and a charge transport layer between the first electrode and the photoelectric conversion layer. The photoelectric conversion layer is configured to absorb light in a wavelength spectrum and converting the absorbed light into an electrical signal. The charge transport layer includes a first charge transport material and a second charge transport material which collectively define a heterojunction.

    Abstract: A device includes a first electrode and a second electrode, an active layer between the first electrode and the second electrode and a plurality of auxiliary layers between the first electrode and the active layer. The auxiliary layers include first and second auxiliary layers, the first auxiliary layer proximate to the active layer, the second auxiliary layer proximate to the second electrode. An energy level of the active layer, an energy level of the first auxiliary layer, an energy level of the second auxiliary layer, and a work function of the first electrode become deeper sequentially or shallower sequentially.

    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.
