<P>PROBLEM TO BE SOLVED: To provide a highly transparent addition-curable silicone composition for sealing solar cells to be bonded preferably to a fluororesin such as Tedlar(R) (polyvinyl fluoride resin) or a PEN resin presented as a back sheet surface layer in addition to glass, and a solar battery module. <P>SOLUTION: The silicone composition for sealing solar cells includes (A) an organopolysiloxane having at least two alkenyl groups bonded with a silicon atom in the molecule represented by formula R<SB POS="POST">a</SB>R'<SB POS="POST">b</SB>SiO<SB POS="POST">(4-a-b)/2</SB>, (wherein R is an alkenyl group, R' is a monovalent hydrocarbon group, 0<a≤2, 0<b<3, and 0<a+b≤3), (B) an organohydrogen polysiloxane having at least two hydrogen atoms bonded with a silicon atom in the molecule, (C) an organic compound having two or more (in total) acryloyl groups and/or methacryloyl groups in the molecule but not having a silicon atom, and (D) an addition reaction catalyst. The silicone composition for sealing solar cells is highly transparent. It is bonded preferably to a back sheet surface layer made of fluororesin such as Tedlar(R) (polyvinyl fluoride resin) or a PEN resin in addition to a glass substrate so as to be used preferably as a material for sealing solar cells. <P>COPYRIGHT: (C)2013,JPO&INPIT |
