Abstract:
The present invention provides a sealing material for a solar cell that seals a solar cell element of a solar cell in a short time in the production of a solar cell module, thereby enabling efficient production of solar cell modules. The sealing material for a solar cell of the present invention has a feature of containing 100 parts by weight of a modified butene-based resin that is produced by graft-modifying a butene-ethylene copolymer having a butene content of 1 to 25% by weight with maleic anhydride and has a total content of the maleic anhydride of 0.1 to 3% by weight, and 0.1 to 15 parts by weight of a silane compound having an epoxy group.
