The present invention provides a solar cell packaging board and a solar cell module using the same, which are excellent in adhesion strength, storage stability, productivity, and environmental resistance of the packaging sheet and the packaging material for a solar cell.nThe present invention relates to a solar battery back sheet having only one base film and a C layer, the C layer having an acrylic resin as a main component, the base film having an A layer and a B layer, the A layer being The polyester resin is a main component, and the A layer contains 5.0% by mass or more and 25% by mass or less of a white pigment, and has a thickness of 5 μm or more, and is disposed on the outermost surface of the other side of the back sheet, and the B layer is mainly composed of a polyester resin. In the component, all of the components of the layer B contain 1.0% by mass or more and less than 5.0% by mass of the white pigment, and the thickness is 70% or more of the entire back sheet. Still another invention is a solar cell backsheet wherein the C layer is obtained from a composition having a reactive functional group acrylic resin and a protected isocyanate compound and an unprotected isocyanate compound. |
