<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 by a roll-to-roll method in 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 4 is laminated and integrated on any one of surfaces of a laminated sheet B having an inorganic oxide deposited film 2 and a second weatherable substrate 3 laminated and integrated on one surface of a first weatherable substrate 1, in this order, wherein the sealing layer 4 contains modified polypropylene-based resin subjected to graft-modification with unsaturated carboxylic acid or its anhydride and having a melting point of 120-170°C, when measured in compliance with JIS K7121. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
