<P>PROBLEM TO BE SOLVED: To provide an inexpensive rear surface protection film for a solar cell module which is superior in environment resistance (hydrolysis resistance and weatherability or the like), and most suitable for the field requiring reflection efficiency and lightweight properties. <P>SOLUTION: The rear surface protection sheet for the solar cell module includes: a film which is made of an ethylene-vinyl acetate copolymer composition and contains a white pigment of 2.0 to 10.0 wt.%; and a polyethylene terephthalate film of which the thickness is 100 μm or more and which contains the white pigment of 2.0 to 10.0 wt.%. In the rear surface protection sheet, the intrinsic viscosity of the polyethylene terephthalate film is 0.65 dl/g or more, the amount of a terminal carboxyl group is 26 equivalent/t or less, and the content of a phosphorus element is 70 wt.ppm or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
