    摘要： The present invention provides encapsulating material for solar cells which facilitates fabricating solar cell modules and has excellent transparency, heat resistance, flexibility, etc., and a solar cell modules. More specifically, the present invention provides encapsulating material for solar cells comprising a non-crystalline or low-crystalline ±-olefin-based copolymer or its composition (I). The most preferable embodiment of the aforementioned copolymer or its composition (I) is resin composition (C) containing 50 to 100 parts by weight of non-crystalline ±-olefin polymer (A) meeting the following requirements: (a) the ±-olefin having 3 to 20 carbon atoms is not less than 20 mol%, (b) practically no melt peak as measured by a differential scanning calorimeter is observed, and (c) the Mw/Mn is not more than 5, and 50 to 0 parts by weight of crystalline ±-olefin polymer (B) (the total of (A) and (B) being 100 parts by weight). The second most preferable embodiment is a non-crystalline or low-crystalline ±-olefin copolymer (D) having the crystallinity of not higher than 40% as measured by use of X rays. The present invention also provides a solar cell module comprising the aforementioned solar cell encapsulating material.

    摘要： The present invention provides a process for producing an encapsulating material for solar cell which makes high-speed crosslinking possible and causes no blister phenomenon without significant restrictions being imposed on the conditions for molding the encapsulating material. The present invention provides a process for producing the encapsulating material for solar cell including impregnating a molded form of an ethylene copolymer with an organic peroxide in a liquid state at normal temperature which shows a decomposition temperature (a temperature at which the half-life period is one hour) of not higher than 150°C. A process for producing the encapsulating material for solar cell in which dialkyl peroxide (A) and an organic peroxide (B) selected from peroxycarbonate and peroxyketal at a ratio by weight of 10/90 to 90/10 of (A) and (B) in a liquid state impregnate the molded form of the ethylene copolymer is a preferable embodiment of the present invention.
