BACK SURFACE PROTECTIVE SHEET FOR SOLAR CELL MODULE AND SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a back surface protective sheet for a solar cell module excellent in design performance, economic efficiency and humidity/heat resistance.

SOLUTION: The back surface protective sheet for the solar cell module comprises at least a laminate (S) on which two or more laminated resin layers are laminated. At least a colored layer (K) composed of a binder resin and a pigment is arranged between either pair of the resin layers. The binder resin of the colored layer (K) is a polyurethane resin (P) obtained by cross linking and setting a urethane-based prepolymer (Ppre) with an isocyanate-based cross linking agent.
