<p><P>PROBLEM TO BE SOLVED: To provide a sealing material for a solar cell, the sealing material being capable of improving the safety during manufacturing, and sufficiently improving cross-linking density of an ethylene-vinyl acetate copolymer (EVA), and suppressing foaming. <P>SOLUTION: A sealing material for a solar cell includes: an ethylene-vinyl acetate copolymer (A) having 25-35 wt.% of a structural unit formed of vinyl acetate; and a mixed organic peroxide (B) comprising an organic peroxide (I) and an organic peroxide (II). A content of the mixed organic peroxide (B) is 0.1-3.0 pts. wt. based on 100 pts. wt. of the ethylene-vinyl acetate copolymer (A), and a weight ratio (I:II) of the organic peroxide (I) and the organic peroxide (II) in the mixed organic peroxide (B) is 100:30-150. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
