Abstract: Disclosed are an organic photoelectronic device including a first electrode and a second electrode facing each other and an active layer interposed between the first electrode and the second electrode, wherein the active layer includes a p-type semiconductor compound represented by the formula C22R1—R12O2N2 and an n-type semiconductor compound having a maximum absorption peak at a wavelength region of about 500 nm to about 600 nm, and an image sensor including the organic photoelectronic device.

Abstract: A solar cell includes a first electrode, a second electrode spaced apart from the first electrode, and a light absorption layer between the first electrode and the second electrode. The light absorption layer includes a first absorption sublayer, a second absorption sublayer and a third absorption sublayer. The first absorption sublayer contacts the first electrode and includes a first quantum dot, the second absorption sublayer is between the first absorption sublayer and the third absorption sublayer and includes a second quantum dot, and the third absorption sublayer contacts the second electrode and includes a third quantum dot. The second quantum dot is larger than the first quantum dot and the third quantum dot.
