<P>PROBLEM TO BE SOLVED: To provide a backsheet for a solar cell module which excels in barrier properties against water vapor and gases and durability, and also is capable of undergoing biological decomposition. <P>SOLUTION: A backsheet for a solar cell module comprises: a barrier film which is a laminate having a resin layer (A) comprising a resin composition containing polyglycolic acid and a barrier layer that is at least one kind selected from the group consisting of layer and a metal foil of a metal or inorganic oxide, which is laminated on at least one side of the resin layer (A); a resin layer (B) comprising a resin composition containing at least one kind selected from fluorine resin, aromatic polyester, aliphatic polyester, polyolefin, or a copolymer thereof; and a resin layer (C) comprising a resin composition containing at least one kind selected from fluorine resin, aromatic polyester, aliphatic polyester, polyolefin, or a copolymer thereof, which is laminated on a surface of the barrier film of the opposite side to the resin layer (B). <P>COPYRIGHT: (C)2012,JPO&INPIT |
