CROSSLINKING AGENT MIXTURE AND SEALING MATERIAL COMPOSITION FOR SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide a crosslinking agent mixture capable of reducing the crosslinking time without damaging crosslink density necessary for heat resistance and free from foaming EVA in the manufacture of a solar cell module, and to provide a sealing composition for a solar cell containing the same.SOLUTION: A crosslinking mixture (A) (component (a-1)+(a-2)=100 wt.%) contains 0.1-45 wt.% t-butyl peroxide-2-ethylhexyl monocarbonate (a-1) and 99.9-55 wt.% t-amylperoxide-2-ethyl hexyl monocarbonate (a-2) expressed by formula (2). The sealing material composition for the solar cell contains 0.1-1.5 pts.wt. crosslinking agent mixture (A) to 100 pts.wt. EVA (B).
