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.
