<p><P>PROBLEM TO BE SOLVED: To provide a solar cell backsheet that is excellent in balance of flexibility and heat resistance, and vapor barrier properties and scratch resistance and can improve photoelectric conversion efficiency by transmitting infrared rays and suppressing heat storage, and a solar cell module provided with the same. <P>SOLUTION: The solar cell backsheet (1) is provided with a first resin layer (11), a second resin layer (12), a third resin layer (13), a water vapor barrier layer (14), and a fourth resin layer (15) successively in this order. The first resin layer (11) is an infrared-transparent colored resin layer. Of the second resin layer (12) and the third resin layer (13), at least the second resin layer (12) is a white-colored resin layer. The fourth resin layer (15) is a back surface protective layer. The thickness H<SB>A</SB>of the first resin layer (11), the thickness H<SB>B</SB>of the second resin layer (12), and the thickness H<SB>C</SB>of the third resin layer (13) satisfy 0.4≤(H<SB>A</SB>+H<SB>C</SB>)/H<SB>B</SB>≤2.4 and 0.7≤H<SB>A</SB>/H<SB>C</SB>≤1.3. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
