<P>PROBLEM TO BE SOLVED: To provide a solar cell module whose sealing material layer has a structure making good use of both the merits of EVA and polyethylene. <P>SOLUTION: A solar cell module 1 is formed by integrally laminating a transparent front substrate 2, a front sealing material layer 3, a solar cell element 4, a rear sealing material layer 5, and a rear protection sheet 6 respectively in the order. A first sealing material sheet constituting the front sealing material layer 3 is an ethylene-vinyl acetate copolymer resin, and a second sealing material sheet constituting the rear sealing material layer 5 is a polyethylene-based resin with a density of 0.940 g/cm<SP POS="POST">3</SP>or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
