Title:
SOLAR CELL SEALING MATERIAL SHEET AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/192860
Kind Code:
A1
Abstract:
The present invention provides: a solar cell sealing material sheet which is mainly composed of a polyolefin resin, and which enables a solar cell module that uses this solar cell sealing material sheet to be effectively suppressed in the formation of air bubbles or bulges at high temperatures; and a method for producing this solar cell sealing material sheet. The above are achieved by means of a method for producing a solar cell sealing material sheet, said method comprising: a step wherein crosslinkable resin pellets are produced by impregnating pellets, which are mainly composed of a polyolefin resin, with a crosslinking agent and a crosslinking assistant; a step wherein the crosslinkable resin pellets are fed into a cylinder through a supply port of an extrusion molding machine, and a resin composition containing the polyolefin resin, the crosslinking agent and the crosslinking assistant is melted and kneaded in the cylinder; and a step wherein the resin composition is extrusion molded into a sheet through a die of the extrusion molding machine. With respect to this method for producing a solar cell sealing material sheet, the crosslinking agent contains a compound that has two or more alkylperoxy groups represented by formula (1) in the structure; and the crosslinking assistant contains triallyl isocyanurate. (1): R1-OO- (In the formula, R1 represents an alkyl group having from 1 to 6 carbon atoms.)
