A glazing includes a transparent substrate coated with a stack of thin layers including at least one functional metal layer and at least two antireflective coatings, each antireflective coating including at least one dielectric layer, so that each functional metal layer is positioned between two antireflective coatings. The stack includes at least one silver-based functional metal layer including at least 95.0% by weight of silver, with respect to the weight of the functional layer, and from 0.5 to 3.5% by weight of zinc, with respect to the weight of zinc and silver in the functional layer.

A thin-film coating applicator assembly is disclosed for coating substrates in outdoor applications. The innovative thin-film coating applicator assembly is adapted to apply performance enhancement coatings on installed photovoltaic panels and glass windows in outdoor environments. The coating applicator is adapted to move along a solar panel or glass pane while applicator mechanisms deposit a uniform layer of liquid coating solution to the substrate's surface. The applicator assembly comprises a conveyance means disposed on a frame. Further disclosed are innovative applicator heads that comprise a deformable sponge-like core surrounded by a microporous layer. The structure, when in contact with a substrate surface, deposits a uniform layer of coating solution over a large surface.

Transfer tapes and methods of making transfer tapes are described. In one aspect, the transfer tape comprises a template layer having a structured surface; a backfill layer disposed on at least a portion of the template layer, the backfill layer having a microstructured surface opposite the structured surface; and a layer disposed adjacent the microstructured surface, wherein the layer disposed adjacent the microstructured surface has a refractive index that differs from the backfill layer. The microstructured surface together with the adjacent layer functions as a diffusive layer, or in other words a diffusive interface. Also described are microoptical glazing and methods of making microoptical glazing as well as insulated glazing units and methods of making insulated glazing units.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

Methods of controlling tint of a tintable window to account for occupant comfort in a room of a building. Some methods include receiving weather feed data from one or more weather services (or other data sources) over a communication network, determining a weather condition based on the weather feed data, and determining a tint level for the tintable window based on the weather condition and based on whether a current time is within a time delay period at sunrise or sunset.

The present invention provides low-reflection coating glass in which a dielectric layer having a higher refractive index and a dielectric layer having a lower refractive index are stacked alternately on a glass substrate.
