ORGANIC PHOTOELECTRONIC DEVICE AND IMAGE SENSOR

摘要

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 (p 1 /n 1 ) 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 (p 2 /n 2 ) 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 (p 3 /n 3 ) of the p-type semiconductor relative to the n-type semiconductor that is greater or less than the first composition ratio (p 1 /n 1 ) and the second composition ratio (p 2 /n 2 ).
