Abstract:
1. A process for producing a solar cell module, comprising: producing an encapsulating material by a process comprising impregnating a molded form of a copolymer of ethylene and a polar monomer with a mixture of an organic peroxide and a crosslinking aid blended at a ratio by weight of 1/0.1 to 0.1/1, wherein the organic peroxide is in a liquid state at room temperature which shows a decomposition temperature (a temperature at which the half-life period is one hour) of not higher than 150° C., wherein the organic peroxide comprises a dialkyl peroxide (A), and an organic peroxide (B) that is selected from the group consisting of peroxycarbonate and peroxyketal, at a ratio by weight of 10/90 to 90/10 of (A) and (B), and wherein after the mixture of the organic peroxide and the crosslinking aid is impregnated into the molded form of the copolymer of ethylene and the polar monomer, the molded form is subjected to aging for not less than three days; providing a solar cell element and at least one protective material; and encapsulating the solar cell element and the at least one protective material with the encapsulating material.
