<P>PROBLEM TO BE SOLVED: To provide a back sheet for a solar cell module which has power generation efficiency accelerated by excellent diffuse reflectivity, and which is excellent in durability, manufacturability, and cost-saving performance. <P>SOLUTION: A back sheet for a solar cell module comprises: a base material sheet; and a reflective layer laminated on the front side of the base material sheet. The reflective layer has white beads and a white binder for the beads. Because the reflective layer has the white beads and the white binder, an uneven surface is formed on the surface, and light can be diffuse-reflected on the uneven surface made of the white beads. This enhances the photoelectric conversion efficiency of the solar cell module to thereby increase power generation efficiency. Further, the invention is excellent in durability, manufacturability, and cost-saving performance because a metal vapor-deposition layer is not required as a reflective layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
