Patent ID: 8080725

Claim:
A photovoltaic module comprising a light receiving surface side supporting member, a sealing material, a solar cell sealed in the sealing material, and a back surface side supporting member, wherein the sealing material includes a first region that is in contact with a light receiving surface of the solar cell, and a second region that is in contact with a back surface of the solar cell, and an adhesive force of the first region to the solar cell is smaller than an adhesive force of the second region to the solar cell, wherein the sealing material of the first region is selected from ethylene vinyl acetate, polyvinyl butyral, silicone resin, urethane resin, acrylic resin, fluoro-carbon based resin, ionomer resin, silane denatured resin, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, polyethylene-based resin, polypropylene-based resin, acid-denatured polyolefin-based resin and epoxy-based resin.
