REAR SURFACE PROTECTION SHEET FOR SOLAR CELL MODULE AND SOLAR CELL MODULE PROTECTED BY SUCH PROTECTION SHEET

摘要

A back protective sheet for a solar cell module, including a three-layered composite film (3a) that has a pair of polybutylene terephthalate outer layers (1 a, 1 a) and a polycarbonate core layer (2a) that is interposed between the outer layers, and a moisture barrier layer (4) that is laminated on the composite film. A solar cell module that has photovoltaic elements that are protected by the back protective sheet. The three-layered composite film may be obtained by coextrusion.
