摘要： Provided in the present invention is a back-face protection sheet for a solar cell module that 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 for a solar cell module 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.

摘要： This invention provides a backside protective sheet for a solar battery module. The protective sheet is formed of a laminated material comprising an alumina vapor-deposited polyester film, a white polyester film, and a polyester film, of which the tensile elongation can be maintained at not less than 60% in both machine direction and transverse direction of the film as measured after storage for 10 hr in such a state that the film is exposed to a high pressure steam of 140°C, stacked in that order on top of each other and the shrinkage upon heat treatment at 150°C for 30 min is not more than 0.5% in both machine direction and transverse direction. The backside protective sheet for a solar battery module has no significant moisture absorption-derived lowering in power generating properties of the module, can effectively reflect incident light for reutilization, and can enhance power conversion efficiency of the solar battery.
