<p><P>PROBLEM TO BE SOLVED: To provide a back protective sheet for a solar cell module that has shape change (shrinkage) suppressed in a laminating step of a module fabricating process while having weatherability, insulation, etc., of high level. <P>SOLUTION: The single-layer or multilayer back protective sheet for the solar cell module includes at least one layer of a weather-resisting resin sheet (A) containing ultra-high molecular weight polyethylene of≥5 dl/g in intrinsic viscosity. The weather-resisting resin sheet (A) has no or plus thermal expansion (both in an MD direction and in a TD direction perpendicular thereto) when heated at 30 to 120°C. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
