Abstract
An organic photoelectronic device includes a first electrode and a second electrode facing each other, photoelectronic conversion layer between the first electrode and the second electrode and including a first material and a second material providing a p-n junction and an interlayer being adjacent to the first electrode between the first electrode and the photoelectronic conversion layer and including a third material, wherein the first material and the third material are an organic material having each energy bandgap of about 1.7 eV to about 2.3 eV, and an image sensor including the same is provided.
Claims16
