Title: LAMINATE, SOLAR CELL REAR SURFACE PROTECTION SHEET USING SAME, AND SOLAR CELL MODULE
Abstract:
A laminate having: a layer (P1 layer) that has a polyester resin as the main component thereof; and a layer (P2 layer) having a resin different from the polyester resin constituting the P1 layer, as the main component thereof, and containing at least one type of particle. The at least one type of particle has an average aspect ratio (major axis/minor axis) of 2–15 and a refractive index of greater than 1.5 and no more than 2.8. A laminate, a solar cell rear surface protection sheet using same, and a solar cell module are provided with good productivity and without delamination, said laminate having an output improvement effect on solar cell modules as a result of utilizing light diffusion by particles having a high average aspect ratio and as a result of having excellent light reflection characteristics and light diffusion properties.
