<P>PROBLEM TO BE SOLVED: To provide a solar battery sealing material having transparency, flexibility, adhesion with various materials, and thermal resistance against the rise in temperature at the time of generating power, and a solar battery module using the solar battery sealing material. <P>SOLUTION: The solar battery sealing material comprises: (A) an ethylene-unsaturated carboxylic acid copolymer in which the content of unsaturated carboxylic acid in the copolymer is 3-30 mass%, and which has a melting point of 50-105°C, (B) an ionomer of ethylene-unsaturated carboxylic acid copolymer in which the content of unsaturated carboxylic acid in the copolymer is 3-30 mass%, and which has a degree of neutralization of 5-40%, and a melting point of 50-105°C, (C) a multifunctional monomer having more than one unsaturated double bond, (D) a multifunctional monomer consisting of a mixture of a multifunctional monomer having more than one unsaturated double bond, and a silane coupling agent having more than one alkoxyl group, and (E) an organic peroxide. The solar battery sealing material includes: 100 pts.wt. of resin of (A) and/or (B), 0.03-5.0 pts.wt. of the multifunctional monomer of (C) or (D), and 0.01-3.0 pts.wt. of the organic peroxide of (E). <P>COPYRIGHT: (C)2012,JPO&INPIT |
