PROCESS FOR PRODUCING SOLAR CELL SEALING MATERIAL

摘要

A process for producing a solar cell sealing material, in which no substantial constraint is posed on molding conditions of sealing material, and in which a high-speed crosslinking can be effected while avoiding any blistering phenomenon; and a process in which a homogeneous solar cell sealing material can be produced in high efficiency. There is provided a process for producing a solar cell sealing material, comprising impregnating a molding of ethylene copolymer with an organic peroxide of = 150°C decomposition temperature (temperature at which the half-life period is 1 hr) being liquid at ordinary temperature. In a preferred mode, there is provided a process for producing a solar cell sealing material, comprising impregnating a molding of ethylene copolymer with dialkyl peroxide (A) and organic peroxide (B) selected from among peroxy carbonates and peroxy ketals used at an (A) to (B) weight ratio of 10/90 to 90/10 in liquid form.
