  • Patent number: 11056597
    Abstract: A photoelectric conversion device includes a photoelectric conversion element formed of a polar material and including no p-n junction, and first and second electrodes provided on the photoelectric conversion element and arranged at an interval. Space-inversion symmetry of a structure of the photoelectric conversion element is broken. The first and second electrodes are each formed of a metal material that generates no substantial potential barrier preventing majority carriers for the photoelectric conversion element from moving from the electrode to the photoelectric conversion element. Light incidence on the photoelectric conversion element without voltage application between the first and second electrodes causes electromotive force to be generated between first and second electrodes, and enables electric current to be continuously taken out from the first and second electrodes.
