PROTECTIVE SHEET FOR BACK SURFACE OF SOLAR CELL MODULE

摘要

Provided is a protective sheet for the back surface of a solar cell module. The protective sheet is lightweight and has excellent water vapor barrier properties. The protective sheet for the back surface of a solar cell module is obtained by layering a base sheet having excellent electrical insulation properties on at least one surface of an aluminum-iron alloy sheet. Preferably the iron content of the aluminum-iron alloy sheet is between 0.7 mass% and 5.0 mass%. The protective sheet for the back surface of a solar cell module preferably has a fluorine resin layer and even more preferably has a heat-adhesive layer.
