发明名称 Multilayer film for solar cell base
摘要 <p>Disclosed is a multi-layer film for use as a solar cell substrate, consisting of a supporting layer and a scattering layer, wherein the supporting layer comprises a thermoplastic crystalline resin, the scattering layer comprises a thermoplastic crystalline resin and particles having a different refractive index from the refractive index of the thermoplastic crystalline resin, the content of the particles in the scattering layer is 0.05 to 20 vol% based on the volume of the scattering layer, the absolute value of the difference between the refractive index of the particles contained in the scattering layer and the refractive index of the thermoplastic crystalline resin in the scattering layer is 0.01 to 1.00, the both surfaces of the multi-layer film have a center line average surface roughness Ra of not more than 50 nm, and the multi-layer film has a total light transmittance Tt of not less than 80 % and a haze ratio of not less than 8 %.</p>
