20090023867Process for Producing Encapsulating Material for Solar Cell - 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.01-22-2009
20090120489Encapsulating Material for Solar Cell - An encapsulating material for solar cell containing a laminated adhesive and heat resistant layer (A) and a buffering layer (B), wherein a difference in flexural modulus between the heat resistant layer (A) and the buffering layer (B) is at least 30 MPa or more, is provided. The adhesive and heat resistant layer (A) is preferably an olefin polymer (a) having a melting point (according to JIS K7121) of 75° C. or higher and having a storage elastic modulus at 150° C. of 1005-14-2009
20100229944ENCAPSULATING MATERIAL FOR SOLAR CELL - The present invention provides an encapsulating material for a solar cell, which is easy to prepare a solar cell module, and excellent in processability, insulating property, non-corrosion property, transparency, heat resistance, flexibility and the like, and a solar cell module prepared by using the same. The encapsulating material for a solar cell is one consisting of a cross-linkable resin composition (A) containing an ethylene-(meth)acrylic ester copolymer as a base polymer, an organic peroxide and a crosslinking aid wherein the decomposition temperature (temperature for a half-life period of one hour) of the organic peroxide is equal to or lower than 150° C., and total compounding amount of the organic peroxide and the crosslinking aid, is in a range of from 0.5 to 5 parts by weight per 100 parts by weight of the base polymer, and compounding ratio of the organic peroxide and the crosslinking aid (organic peroxide/crosslinking aid) is in a range of from 1/5 to 1/0.1, in weight ratio.09-16-2010
20110061735CROSSLINKABLE ETHYLENE COPOLYMER COMPOSITION, ENCAPSULATING SHEET FOR SOLAR CELL ELEMENT COMPOSED OF THE SAME, AND SOLAR CELL MODULE USING THE SHEET - The present invention provides a crosslinkable ethylene copolymer composition which is superior in transparency, heat resistance, adhesive property, flexibility, moldability, durability, and the like, as well as in insulating property, and which shows less decrease in adhesive property with time and can maintain the adhesive property for a long period, and a crosslinkable sheet composed of said composition, and an encapsulating sheet for solar cell and a solar cell module. More in detail, the present invention relates to a crosslinkable ethylene copolymer composition comprising a dialkoxysilane having a double bond in a ratio of 3 parts by weight or less to 100 parts by weight of ethylene copolymer, and a crosslinked sheet of said composition, and further to an encapsulating sheet for solar cell composed of said composition and a solar cell module using the sheet.03-17-2011
20110105681ETHYLENE COPOLYMER COMPOSITION, SHEET FOR SEALING A SOLAR CELL ELEMENT, AND SOLAR CELL MODULE - An ethylene copolymer composition which includes a zinc ionomer containing, as a main component, a copolymer having a constituent unit derived from ethylene and a constituent unit derived from (meth)acrylic acid, and a dialkoxysilane having an amino group, is provided. This makes it possible to increase the stability during sheet production. It is preferable that the content ratio of the dialkoxysilane is 15 parts by mass or less based on 100 parts by mass of the zinc ionomer.05-05-2011
20110108094LAMINATED SHEET FOR SOLAR CELL AND SOLAR CELL MODULE USING THE SAME - Provided is a laminated sheet for solar cell having a back sheet base material including a fluoro-resin or a polyester resin, and a sealing material layer which includes an ethylene copolymer composition containing a copolymer of an ethylene and a polar monomer which has a polar group selected from a group consist of a carboxylic acid group and a group derived from a carboxylate and a dialkoxysilane having an amino group is laminated on a surface of the back sheet base material where a chemical treatment or a physical treatment for improving adhesiveness has been applied, by a melt extrusion lamination method. Thereby, a laminated sheet having excellent productivity and excellent interlayer adhesion strength between the back sheet and the sealing material is obtained.05-12-2011
20110272026MULTILAYER SHEET, ENCAPSULANT FOR SOLAR CELL ELEMENT, AND SOLAR CELL MODULE - A multilayer sheet including an (A) layer containing an ethylene type zinc ionomer as a main component and a silane coupling agent, and a (B) layer containing a polyethylene-based copolymer with a melting point of 90° C. or higher as a main component and a silane coupling agent having a content ratio with respect to the resin material that is lower than a content ratio of the silane coupling agent with respect to resin material in the (A) layer, wherein the total thickness of the (A) layer and the (B) layer is from 0.1 to 2 mm. Such multilayer sheet may be superior in adhesive strength, durability and heat resistance, and obtained at a suppressed cost.11-10-2011
20110319566SHEET FOR SOLAR CELL ENCAPSULANT AND SOLAR CELL MODULE - Provided is a sheet for a solar cell encapsulant containing (A) an ethylene-based polymer having a melting point of 90° C. or higher and containing an ethylene-derived constituent unit as a main component; (B) an ethylene-vinyl acetate copolymer having a vinyl acetate-derived constituent unit at a content ratio of from 19% to 40% by mass; and (C) a silane coupling agent having an amino group.
