BACKSIDE PROTECTIVE SHEET FOR SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a backside protective sheet for a solar cell module, which is excellent in scratch resistance.SOLUTION: The backside protective sheet for a solar cell module comprises at least a polyester film and an ultraviolet protective layer. The ultraviolet protective layer contains a resin component and inorganic particles. The light transmittance at 360 nm of the ultraviolet protective layer is 5% or less. The center surface average roughness of the ultraviolet protective layer is 0.05 to 0.12 μm inclusive.SELECTED DRAWING: None
