BACK-FACE PROTECTION SHEET FOR SOLAR CELL MODULE, AND SOLAR CELL MODULE USING SAME

摘要

Provided in the present invention is a back-face protection sheet for a solar cell module that exhibits excellent adhesion strength and rupture 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 rupture 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.
