<P>PROBLEM TO BE SOLVED: To provide a polyethylene-based crosslinked sealing material. <P>SOLUTION: A composition containing low density polyethylene with a density of 0.900 or lower, a crosslinking agent, and a crosslinking auxiliary agent consisting of a polyfunctional vinyl monomer and/or a polyfunctional epoxy monomer is formed, and thereafter crosslinking processing is carried out so as to have a gel fraction of 2% or more and 80% or less. The composition is an olefinic sealing material that has already been crosslinked, therefore a separate crosslinking step is not needed at the time of a modularization into a solar cell, and also the flow can be suppressed in the modularization. <P>COPYRIGHT: (C)2013,JPO&INPIT |
