  • Publication number: 20120073655
    Abstract: A package for storing or transporting a solar cell sealing film includes: the solar cell sealing film containing a silane compound and/or a silane-modified resin; and a package bag packaging the solar cell sealing film. The absolute humidity inside the package is 1 to 15 g/m3. The package can store or transport the solar cell sealing film while adhesive force thereof with a substrate, solar cells, etc. is kept at a practicable level or higher. Furthermore, the package can reduce the breakage of the solar cells caused by an external shock while a solar cell module operates and the corrosion of electrodes caused by water etc. from the atmosphere.
