Abstract
An organic photoelectronic device includes a first electrode and a second electrode facing each other, and first and second photoelectronic conversion layers between the first electrode and the second electrode. The first and second photoelectronic conversion layers include a p-type semiconductor and an n-type semiconductor. The first photoelectronic conversion layer has a first composition ratio (p/n) of the p-type semiconductor relative to the n-type semiconductor, the second photoelectronic conversion layer has a second composition ratio (p/n) of the p-type semiconductor relative to the n-type semiconductor, and the first composition ratio (p/n) is greater than the second composition ratio (p/n).
