摘要:
An object of the present invention is to provide a method for producing a resin composition for solar cell sealing material which is capable of lowering a cost by shortening of a processing time and has good storage stability. Further, another object of the present invention is to provide a solar cell sealing material having excellent transparency due to no generation of lumps therein by using the obtained resin composition for solar cell sealing material. A method for producing a resin composition for solar cell sealing material according to the present invention includes: preparing an ethylene-vinyl acetate copolymer (A) containing a vinyl acetate unit in an amount of 25 to 35 wt% and a crosslinking agent (B), whose impregnation weight with respect to 1 g of the ethylene-vinyl acetate copolymer (A) per 24 hours at a temperature of 23°C is in the range of 40 to 80 mg, as raw components; and impregnating the crosslinking agent (B) into the ethylene-vinyl acetate copolymer (A) at a temperature of 15 to 80°C.

A film-reinforced glass, characterized in that it comprises a sheet of flat glass, an organic resin membrane comprising EVA as a main component laminated on the glass and, laminated on the membrane, a film comprising an organic polymer, these laminated materials being crimped with each other. The organic resin membrane may have electrical conductivity, and a hard coat layer may be formed on the film. The film-reinforced glass can be used for producing a thin glass which is excellent in impact resistance and the resistance to being cut through.

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.

A method is used to make a glass-covered panel (10), comprising a base panel (11) made of wood or wood substitute material, with or without compartments, and at least a glass sheet (15), associated with at least one face (13) of the base panel (11). The method comprises at least a preliminary step of preparing the base panel (11) with a desired shape and size. The method also comprises at least a first framing step, in which edging elements (14) are associated with one or more sides of the base panel (11), an intermediate covering step, in which the glass sheet (15) is applied to the said (13), and a final finishing step in which material is removed from at least part of one or more edges of the glass sheet (15).

An electronic device module comprises: A. At least one electronic device, e.g., a solar cell, and B. A polymeric material in intimate contact with at least one surface of the electronic device, the polymeric material comprising an ethylene multi-block copolymer. Typically, the polyolefin material is an ethylene multi-block copolymer with a density of less than about 0,90 grams per cubic centimeter (g/cc). The polymeric material can fully encapsulate the electronic device, or it can be laminated to one face surface of the device. Optionally, the polymeric material can further comprise a scorch inhibitor, and the copolymer can remain uncrosslinked or it can be crosslinked.
