(Problem) The solar cell backsheet which maintains the outstanding gas barrier property and is excellent in weatherability and light-shielding property is provided. (Solution means) A solar cell back sheet having a light-shielding colored layer and a weather-resistant polyester-based resin layer and further having a gas barrier layer including a weather-resistant coat layer and an inorganic thin film layer, wherein the weather-resistant coat layer is (A) a crosslinked product of polycaprolactone polyol and / or polycarbonate polyol, (B) a crosslinked product of modified polyvinyl alcohol, and (C) at least one selected from the group consisting of an ultraviolet stabilizer, an ultraviolet absorber, and a cycloalkyl group. The solar cell back sheet which consists of at least 1 sort (s) chosen from the acryl-type copolymer which has a group of species. |
