Appl. No.:

13/484116

Inventors:

ROBERT C. GROMMESH - St. Louis Park MN, US
BENJAMIN James ZURN - Roseville MN, US
RICHARD Alan PALMER - Delano MN, US

Assignee:

CARDINAL IG COMPANY - Eden Prairie MN

International Classification:

E06B 3/663

US Classification:

156109, 428447, 428213, 428215, 428189, 428462, 4284258, 428419

Abstract:

An insulating glass unit may include a spacer positioned between opposing panes of material to define a between-pane space. The spacer may seal the between-pane space from gas exchange with a surrounding environment and hold the opposing panes in a spaced-apart relationship. In some examples, the spacer includes a primary sealant layer, a secondary sealant layer, and a gas diffusion barrier layer positioned between the primary sealant layer and the secondary sealant layer. The gas diffusion barrier layer may define a first side and a second side opposite the first side. Depending on the application, the first side of the gas diffusion barrier layer may be positioned in contact with the primary sealant layer while the second side of the gas diffusion barrier layer is positioned in contact with the secondary sealant layer.

International Classification:

H01L 31/00
H01L 21/50

US Classification:

136256, 438 64, 257E21499

Abstract:

A photovoltaic glazing assembly including first and second substrates, at least one being formed of a light transmitting material. The assembly includes a photovoltaic coating over at least the central region of a surface of the first substrate or the second substrate. In some embodiments, a seal system encloses a gas space between the substrates and optionally has a thickness of between approximately 0.01 inch and approximately 0.1 inch. Certain embodiments provide a flexible and electrically non-conductive retention film over the photovoltaic coating. Additionally or alternatively, the assembly can have a peripheral seal system with relative dimensions in certain ranges. Advantageous manufacturing methods are also provided.

International Classification:

H01L 31/042
B32B 37/14

US Classification:

136251, 156145

Abstract:

A photovoltaic panel includes a substrate, a photovoltaic coating extending over, and being adhered to, a central region of a major surface of the substrate, and a flexible and electrically non-conductive film overlaying the photovoltaic coating, such that the photovoltaic coating is sandwiched between the film and the substrate. An assembly, which includes the photovoltaic panel, further includes a second substrate, which is joined to the first substrate, for example, by a seal member, such that an air space is enclosed between the film and the second substrate.

US Classification:

156269, 156276, 156383, 156511

Abstract:

Some methods, and corresponding apparatus, for manufacturing photovoltaic subassemblies cause a plurality of desiccant beads to be adhered to an adhesive surface of sheet-like material; the sheet-like material is then, preferably, adhered to an exposed surface of a flexible and electrically non-conductive film, that covers a photovoltaic coating of a first substrate of the subassembly, such that the desiccant beads are held between the sheet-like material and the exposed surface. Some other methods, either alternatively or in addition to the above, include steps for applying the film, that covers the photovoltaic coating, wherein an opening, through the film, is cut, and then aligned, with lead wires of the photovoltaic coating, in the midst of applying the film.

International Classification:

E06B 3/66
B32B 37/14

US Classification:

428 34, 156103

Abstract:

A glazing assembly includes a functional coating extending over, and being adhered to a central region of an inner major surface of a first substrate, which opposes a second substrate, whose inner surface includes a central region facing the functional coating; a spacer member, which is directly adhered to aligned peripheries of the inner major surfaces, joins the substrates, such that an airspace is enclosed between the central regions thereof. The spacer member may be pre-formed from a material having properties that result in a relatively low moisture vapor transmission rate therethrough, and may have a pre-formed footprint that matches a shape of the periphery of each of the substrates. A silane primer may be applied to the peripheries of the substrates to improve hydrolytic stability of the adhesion between the substrates and the spacer member.

US Classification:

136251, 156329

Abstract:

A photovoltaic assembly including first and second substrates joined together and spaced apart, on either side of an airspace, by a seal system formed of a first seal and a second seal, the second seal comprising one or more silyl terminated polyacrylate polymers. A photovoltaic functional coating is disposed over a second major surface of one of the substrates, which faces the second major surface of the other substrate. Lead wires are coupled to bus bars and/or electrical contacts affixed to the functional coating and routed out from the airspace. Affixing the seal system to the first and second substrates, in order to join the substrates together, may be accomplished by applying pressure to the substrates.

Abstract:

The present invention in some embodiments provides sputter deposition techniques for applying thin film and thereafter applying over the sputtered film a temporary protective film. The thin film can optionally be applied by sputtering a target in a gaseous sputtering atmosphere containing an oxidizing gas and/or an inert gas. The invention in some embodiments relates to an insulating glazing unit or a monolithic pane having a thin film coating, deposited for example by sputtering, on at least one major surface, the thin film coating carrying a temporary protective film. The invention also provides embodiments involving high efficiency methods for producing such products.
