Abstract: A non-light-emitting variable transmission device can include an active stack; a transparent conductive layer overlying the active stack; an antireflective layer overlying the transparent conductive layer and defining a hole; and a bus bar comprising a conductive tape that extends into the hole and contacts the transparent conductive layer. Proper selection of materials and design of a bus bar can allow an electrical connection to be made to the transparent conductive layer without the need to cut an underlying transparent conductive layer. A method of forming the non-light-emitting variable transmission device can include patterning the antireflective layer to define the hole that extends to the transparent conductive layer. Improved control in patterning allows the antireflective layer to be relatively thin and not remove too much of the underlying transparent conductive layer.

Abstract: An insulating glazing unit includes two panes and a spacer, with two pane contact surfaces. A first and second pane contact surfaces are connected to, respectively, a first and a second pane via a sealant to form a glazing interior space and a glazing exterior space. At least one pane is provided on the side facing the glazing interior space at least partially with an electrically conductive coating and/or an electrically controllable functional element and two bus bars are provided for electrically contacting the electrically conductive coating and/or the electrically controllable functional element. A bus bar includes an electrically conductive adhesive tape. The electrically conductive adhesive tape includes an electrically conductive adhesion layer, a conductor track, and an opaque, electrically insulating cover.

Abstract: An electroactive device comprising a stack comprising a first electrode and a second electrode; and an electroactive layer disposed between the first and second electrodes, wherein the stack comprises a mitigated area essentially free of material corresponding with the first electrode, and wherein at least a portion of the second electrode and electroactive layer, as contained in the mitigated area, are functional.

Abstract: A stack of layers can be formed adjacent to a substrate before any layer within the stack is patterned. In an embodiment, combinations of substrates and stacks can be made and stored for an extended period, such as more than a week or a month, or shipped to a remote location before further manufacturing occurs. By delaying irreversible patterning until the closer to the date final product will be shipped to a customer, the likelihood of having too much inventory of a particular size or having to scrap windows for a custom order that was cancelled after manufacturing started can be substantially reduced. Further, particles between layers of the stack can be avoided. The process flows described are flexible, and many of the patterning operations in forming holes, openings, or the high resistance region can be performed in many different orders.
