Abstract
Provided are a multilayer sheet superior in weather resistance, heat resistance, and moisture proofness and also favorable in interlayer adhesiveness, and a back sheet for solar cells and a solar cell module prepared by using the same. The multilayer sheetis prepared by laminating a polyolefin-based resin layerhaving a melt flow rate, as determined by the method A specified in JIS K7210, of 0.5 to 25 g/10 minutes at 230° C. under a load of 2.16 kg and a polyvinylidene fluoride-based resin layerhaving a melt flow rate, as determined by the method A specified in JIS K7210, of 0.5 to 25 g/10 minutes at 230° C. under a load of 2.16 kg, via an adhesion resin layerof a conjugated diene-based polymer, a conjugated diene-based copolymer, or the hydride thereof having a melt flow rate, as determined by the method A specified in JIS K7210, of 0.1 to 50 g/10 minutes at 230° C. under a load of 2.16 kg. A back sheet prepared by using the multilayer sheetis layered on a sealing material of a solar cell, to give a solar cell module.
