<P>PROBLEM TO BE SOLVED: To provide a rear surface protecting sheet for a solar battery which is capable of maintaining an initial high reflection factor for a long period of time without generating yellowing or deterioration while being excellent in mechanical strength and thermal resistance. <P>SOLUTION: The rear surface protecting sheet for solar battery is constituted of a polyolefin-based resin composition which contains polyolefin resin 100 pts.wt. and a rutile type titanium dioxide 10-50 pts.wt. whose mean particle diameter is 0.005-0.25 micrometers and further contains an inorganic filler 1-30 pts.wt. except the rutile type titanium dioxide and its the thickness thereof is 0.05-1 mm. Consequently, the sheet is excellent in weathering ability, thermal resistance and light reflecting property, and light incident into the solar battery module which employs the rear surface protecting sheet for the solar battery is reflected stably to the side of a power generating element for a long period of time, thereby favorably maintaining the power generating performance of the solar battery module for a long period of time. <P>COPYRIGHT: (C)2010,JPO&INPIT |
