Patent ID: 10224448

Abstract:
A solar cell module including: a solar cell; a first protection member provided on the light receiving surface side of the solar cell; a second protection member provided on the rear surface side of the solar cell; an encapsulant layer, including a first encapsulant layer disposed between the solar cell and the first protection member, and a second encapsulant layer disposed between the solar cell and the second protection member, which seals the solar cell; and a wavelength conversion substance, contained in at least the first encapsulant layer, which absorbs light having a specified wavelength, and converts the wavelength. The concentration of the wavelength conversion substance is higher in the first encapsulant layer than in the second encapsulant layer, and a resin constituting the second encapsulant layer has a smaller diffusion coefficient of the wavelength conversion substance than the diffusion coefficient of a resin constituting the first encapsulant layer.
