发明名称 SOLAR CELL BACKSHEET, PRODUCING METHOD OF THE SAME, AND SOLAR CELL MODULE
摘要 A solar cell backsheet, which is arranged in contact with a sealing material of a cell-side substrate on which a photovoltaic element is sealed with the sealing material, the solar cell backsheet including a polyester film base material and at least one polymer layer arranged thereon, wherein the polyester film base material has a carboxyl group content of from 1 eq/ton to 15 eq/ton, a minute endothermic peak temperature Tmeta (° C.) of 220° C. or lower as determined by differential scanning calorimetry, and an average elongation retention ratio of 10% or more as determined after being left to stand for 72 hours under conditions of a temperature of 125° C. and a relative humidity of 100% RH; and the at least one polymer layer comprises at least a fluorocarbon-based polymer, has a crosslinked structure derived from at least one crosslinking agent selected from carbodiimide-based compounds and oxazoline-based compounds and is formed by coating.
