Abstract
A solar cell module includes a plurality of electric power generation units. Each of the plurality of electric power generation units includes a solar cell element and a light guide unit having a first surface and a second surface positioned opposite to the first surface and configured to guide light toward the solar cell element between the first surface and the second surface. The plurality of the light guide units included in the plurality of electric power generation units include a first light guide unit having a first fluorescent material that emits first light upon receipt of light incident from the first surface, and also includes at least one light guide unit of a second light guide unit having a second fluorescent material that emits second light having a different wavelength from the first light upon receipt of light incident from the first surface and a third light guide unit in which a shape of the second surface is designed so that part of light incident from the first surface is reflected from the second surface and travels in a direction non-parallel to that before reflection.
