    摘要： A solar cell module includes a light guide and a solar cell element. The light guide has a light incident surface and a light exit surface having an area smaller than the light incident surface and contains a plurality of optical functional materials. In the light guide, part of external light incident on the light incident surface is absorbed by the plurality of optical functional materials, Foerster energy transfer occurs among the plurality of optical functional materials, and light emitted by the optical functional material having the longest peak wavelength of the emission spectrum among the plurality of optical functional materials is collected to and exits from the light exit surface. The solar cell element receives light exiting from the light exit surface of the light guide. The spectral sensitivity of the solar cell element at the peak wavelength of the emission spectrum of the optical functional material having the longest peak wavelength of the emission spectrum among the plurality of optical functional materials is higher than the spectral sensitivity of the solar cell element at peak wavelengths of the emission spectrums of the other optical functional materials contained in the light guide.

    摘要： A light diffusing member includes a base material having a light transmitting property; a plurality of light blocking sections that are formed in a scattered manner at one surface of the base material; and a light transmissive material layer that is formed at the one surface of the base material. A thickness of the light transmissive material layer is larger than a thickness of each light blocking section. The light transmissive material layer has hollow portions in regions where the light blocking sections are formed. Each hollow portion has a shape in which a cross-section area when each hollow portion is cut at a plane that is parallel to the one surface of the base material is large on a side of the corresponding light blocking section and becomes gradually smaller with increasing distance from the corresponding light blocking section. A portion of the light transmissive material layer other than where the hollow portions are formed is a light transmitting section.
