REAR SURFACE PROTECTIVE SHEET FOR SOLAR CELL MODULE, AND SOLAR CELL MODULE USING THE PROTECTIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a protective sheet for a solar cell module excellent in weather resistance, adhesiveness, abrasion resistance, and heat resistance and high in durability.

SOLUTION: The protective sheet for the solar cell module configured by laminating at least a protective layer (A) and a base material (B) made of a thermoplastic resin in this order from a rear surface outer side of the solar cell module is characterized in that the protective layer (A) is a layer formed by applying an ionizing radiation hardening resin composition and then irradiating it with ionizing radiation to be crosslinking-cured such that the reaction rate of a radical polymerization unsaturated group in the ionizing radiation hardening resin is at least 60% and the universal hardness of its surface is not more than 50 N/mm2, and the thickness of the protective layer (A) is at least 0.5μm and less than 10μm.
