The utility model relates to a glued membrane is crowded altogether to three -layer that contains light diffusing particle, it adopts three -layer crowded structure altogether, and white EVA, the transparent EVA of both sides laminating are adopted to the intermediate level, there is light diffusing particle in the transparent EVA layer. Light diffusing particle is circular, ellipse and/or polygon. The utility model discloses the stratum lucidum of crowding the three -layer altogether the glued membrane adds light diffusing particle for sunlight that white layer reflected promotes photoelectric conversion efficiency once more by the diffused reflection greatly.
