Sealing material for solar cell, protective sheet for solar cell, and process for production of solar cell module

The sealing material for a solar cell according to claim 1, wherein the silane compound is a silane compound represented by the following general formula (I):

A protective sheet for a solar cell comprising a fluoropolymer sheet integrally laminated onto one surface of the sealing material for a solar cell according to claim 1.

A process for production of a solar cell module, comprising a lamination step in which a laminated sheet is produced by continuously laminating the sealing material for a solar cell according to claim 1 onto a solar cell element mounted in a solar cell including the solar cell element formed in a thin film form on a flexible elongate substrate; and an sealing step in which the solar cell element of the solar cell is sealed with the sealing material for a solar cell by heating the laminated sheet while applying a pressing force thereto in the thickness direction thereof.

The process for production of a solar cell module according to claim 7, wherein the lamination step is a step in which a first protective sheet for a solar cell including a fluoropolymer sheet integrally laminated as the transparent top side protective material onto one surface of a sealing material for a solar cell comprising 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 is laminated onto the top surface of the solar cell with the solar cell being opposed to the sealing material for a solar cell, and a second protective sheet for a solar cell including a fluoropolymer sheet integrally laminated as the bottom side protective material onto one surface of a sealing material for a solar cell comprising 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 is laminated onto the bottom surface of the solar cell with the solar cell being opposed to the sealing material for a solar cell, so that the laminated body is produced.
