摘要：
A photoelectric conversion device includes: a wavelength converting region that absorbs ambient light to generate electrons and holes, and recombines the generated electrons and holes to generate monochromatic light and a photoelectric conversion region that has a p-n junction or p-i-n junction, absorbs the monochromatic light generated in the wavelength converting region to generate electrons and holes, and separates and moves the electrons and holes generated by absorption of the monochromatic light. The wavelength converting region includes: a carrier generating region that generates the electrons and holes a light emitting region that generates the monochromatic light and a carrier selective transfer region that is disposed between the carrier generating region and the light emitting region and that, of the electrons and holes generated in the carrier generating region, moves those electrons and holes having specific energies difference there between to the light emitting region.
