Abstract
A photoelectric conversion device includes a first electrode and a second electrode facing each other, an organic photoelectric conversion layer between the first electrode and the second electrode, and a charge auxiliary layer between the first electrode and the organic photoelectric conversion layer. The organic photoelectric conversion layer is configured to absorb light in at least a portion of a wavelength spectrum of incident light and to convert the absorbed light into an electrical signal. The charge auxiliary layer includes a metal and an oxide. The oxide may be an oxide material that excludes silicon oxide such that the charge auxiliary layer does not include silicon oxide.
