  • Publication number: 20120184061
    Abstract: Disclosed are a sealing material sheet for a solar cell module and a method of manufacturing a solar cell module capable of reducing damage to a photoelectric conversion cell and leakage of a sealing material during manufacturing of a solar cell module, and easily manufacturing a high-quality solar cell module. A sealing material sheet for a solar cell module includes transparent resin (A) exhibiting an MFR (190° C., 2.16 kg load) of 10 to 20 g/10 min and transparent resin (B) exhibiting an MFR (190° C., 2.16 kg load) of 30 to 40 g/10 min. The mass ratio ? (=WA/WB) of the transparent resin (A) (mass: WA) and the transparent resin (B) (mass: WB) is 0.7 to 1.5. A solar cell module uses the sealing material sheet for a solar cell module.
