Abstract: A fullerene derivative may be included in photoelectric devices and image sensor. Optical absorption characteristics of a thin film including the fullerene derivative may be shifted toward a short wavelength compared with those of the thin film including the unsubstituted C60 fullerene, for example, a thin film including the fullerene derivative may be associated with a peak absorption wavelength (λmax) that is be shorter than that of a thin film including the unsubstituted C60 fullerene.
