<P>PROBLEM TO BE SOLVED: To provide a backside protective film for a solar cell, a method of producing the same, and a solar cell module, which have excellent low heat storage, heat resistance, flexibility, and scratch resistance when receiving light such as sunlight on a surface of a first resin layer side, excellent adhesiveness to a member containing ethylene-vinyl acetate copolymer, and excellent durability to a thermal cycle. <P>SOLUTION: A backside protective film (1) for a solar cell of the present invention comprises a first resin layer (11) and a second resin layer (12) placed on one surface side of the first resin layer. The first resin layer is a resin layer (with a thickness of 10-400 μm) containing a rubber-containing aromatic vinyl resin with a maximum temperature of a glass transition temperature of 90°C to 120°C and an infrared-ray permeable colorant. The second resin layer is a resin layer (with a thickness of 10-400 μm) made of a film containing a saturated polyester resin and a white-based colorant and having a rate of change in size of ±0.5% between before and after leaving at 135°C for 30 minutes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
