Abstract: Provided is a power generation system including a photovoltaic unit arranged in a flight vehicle which provides a wireless communication service to a user terminal in a communication area formed over a ground, an electric storage unit which is connected to the photovoltaic unit and stores electric power generated by the photovoltaic unit, and a power conditioner which converts the electric power generated by the photovoltaic unit. The electric storage unit is connected, for example, in parallel to connection between the photovoltaic unit and the power conditioner, and the electric power stored in the electric storage unit is supplied to the power conditioner.

Abstract: A photoelectric conversion apparatus includes: a photoelectric conversion element which converts light energy of incident light into electric energy; a first wavelength conversion layer disposed in contact with a light receiving surface of the photoelectric conversion element; and a second wavelength conversion layer disposed on a side of a surface of the first wavelength conversion layer opposite to a surface in contact with the photoelectric conversion element. The first wavelength conversion layer contains a first wavelength conversion material which converts a wavelength of light in a first wavelength region. The second wavelength conversion layer contains a second wavelength conversion material that converts a wavelength of light in a second wavelength region. An upper limit value of the first wavelength region is different from that of the second wavelength region, and/or a lower limit value of the first wavelength region is different from that of the second wavelength region.
