Patent ID: 8822811

Claim:
A solar cell module comprising solar cells, a sealing material that covers the solar cell, and a back protective sheet wherein the back protective sheet is directly laminated on the sealing material and is provided at the other side face of a light receiving surface of the solar cell module, the back protective sheet comprises a base sheet composed of a resin sheet, a fluorine resin layer containing a fluorine-containing resin and a pigment and an adhesive layer, the adhesive layer is directly laminated on the sealing material, the base sheet is laminated on the adhesive layer, the fluorine resin layer is directly coated on the base sheet, and the arithmetic average roughness (Ra) of the fluorine resin layer as measured in compliance with JIS B0601-1994 is 1.0 μm or more the pigment is at least one pigment selected from the group consisting of a rutile form titanium dioxide and hydrophobic silica, the density of the pigment in the fluorine resin layer in the direction of thickness of the fluorine resin layer is higher on the side opposite from the base sheet than on the side facing the base sheet, and the back protective sheet is configured to reflect light incident from the base sheet at the pigments of the fluorine resin layer toward the solar cell.
