摘要:
This specification generally relates to aqueous compositions for preparing UV stable fire-resistant interlayers. It also relates to UV stable fire-resistant glazing laminates comprising such interlayers, the use of such glazing laminates in construction, and constructions comprising such glazings. An example aqueous composition comprises a mixed alkali metal silicate of general formula SiO2·M2O, where M is K or Na, and other organic and inorganic additives. Glazings with interlayers made with such aqueous compositions are simple to prepare and demonstrate good UV stability and fire-protection properties.

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.

Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

An encapsulant sheet for a solar cell contains not less than 91% but less than 99% by mass of an ethylene-unsaturated ester copolymer (A), more than 1% but not more than 9% by mass of an olefin resins (B), 0.001 parts to 5 parts by mass of silicon dioxide and 0.001 to 0.5 parts by mass of a silane coupling agent, where the sum total of the content of the ethylene-unsaturated ester copolymer (A) and the content of the olefin resin (B) is taken as 100% by mass. The content of the silicon dioxide and the content of the silane coupling agent are relative to the total content of the ethylene-unsaturated ester copolymer (A) and the content of the olefin resin (B) being taken as 100% by mass. The encapsulant sheet is excellent in insulating property, storage stability, transparency, and durability of adhesion to glass.

Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.
