Abstract: A back-face protection sheet for a solar cell module exhibits excellent adhesion strength and tensile strength even under a high-temperature and high-humidity environment, by using a plastic film that has excellent characteristics such as electrical insulation characteristic, heat resistance, dimension stability, mechanical strength, weatherability, and water resistance, and using a two-part type lamination adhesive having excellent weatherability. The back-face protection sheet is made to have excellent adhesion strength and tensile strength for a long period of time, even under a high-temperature and high-humidity environment, by improving weatherability (hydrolysis resistance) as base material films, and giving weatherability (hydrolysis resistance) to the two-part type lamination adhesive to be used in pasting together the base material films.

Abstract: A backside protection sheet for a solar cell module comprising a stacked material formed by successively stacking an alumina vapor deposited polyester film, a white polyester film and a polyester film in which 60% or more of tensile elongation is maintained in both a machine direction and a transverse direction of the film after the film is stored in high-pressure steam of 140° C. for 10 hours, wherein a shrinkage percentage of said backside protection sheet at a time of heat-treating at 150° C. for 30 minutes is 0.5% or less in both the machine direction and the transverse direction.
