Abstract: A solar cell module includes: solar cells each having a first main surface and a second main surface; a front-side transparent protective member disposed on a first main surface-side of the solar cells; a front-side transparent encapsulant layer disposed between the front-side transparent protective member and the solar cells; a back-side protective member disposed on a second main surface-side of the solar cells; a back-side white encapsulant layer disposed between the back-side protective member and the solar cells; and a back-side transparent encapsulant layer disposed between the back-side white encapsulant layer and the solar cells, wherein a thickness of the back-side transparent encapsulant layer in a vicinity of an edge portion of the second main surface of the solar cells is less than a thickness of the back-side transparent encapsulant layer in a region between the solar cells that are neighboring to each other.

Abstract: A solar cell module may include: solar cells; a colored layer serving as a first reflective layer disposed at the rear sides of the solar cells and including a coloring agent with a higher refractive index than the main material of the colored layer; an intermediate transparent layer disposed at the rear side of the colored layer and having a higher transmission factor than the colored layer; and a protective member at the rear side of the module, serving as a second reflective layer disposed at the rear side of the intermediate transparent layer, including a whitened portion having a higher refractive index than the main material of the protective member, and having a higher refractive index for the entire layer than the intermediate transparent layer. A sealing member at the rear side of the module includes the colored layer and the intermediate transparent layer.
