Abstract:
The invention provides a back sheet including a water-impermeable sheet and a film firmly bonded to each other and exhibiting excellent adhesiveness to an EVA encapsulant layer of a solar cell module even without corona discharge treatment on the film surface. The back sheet of the invention is a back sheet for solar cell module, including a water-impermeable sheet and a film. The film is disposed on at least one side of the water-impermeable sheet and is formed from a coating containing a fluorine-containing copolymer. The fluorine-containing copolymer contains a C2-C3 perhaloolefin structural unit, a vinyl acetate structural unit, a hydroxy-containing vinyl monomer structural unit, and a carboxy-containing monomer structural unit.
