<p><P>PROBLEM TO BE SOLVED: To provide a rear-surface protecting sheet for a solar cell, which can prevent the generation of a gas in manufacturing a solar cell module, is superior in flexibility, heat resistance and bondability, and can be laminated on the solar cell through a roll-to-roll method, when manufacturing the solar cell module. <P>SOLUTION: The rear-surface protecting sheet A for a solar cell is formed, in such a way that a sealing layer 3 is laminated and integrated on any one of surfaces of a laminate sheet B having a weatherable substrate 2 laminated and integrated on a metal foil 1, wherein the sealing layer 3 contains 100 pts.wt. of modified polypropylene-based resin subjected to graft-modification with unsaturated carboxylic acid or its anhydride and having a melting point of 120-170°C, as measured in conformance with JIS K7121, and 0.001-20 pts.wt. of silane compound represented by R<SP>1</SP>Si(OR<SP>2</SP>)<SB>3</SB>. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
