Abstract
Embodiments described include bus bars for electrochromic or other optical state changing devices. The bus bars are configured to color match and/or provide minimal optical contrast with their surrounding environment in the optical device. Such bus bars may be transparent bus bars.
Claims34
An insulated glass unit (IGU) comprising:
- first and second substantially transparent substrates;
- a spacer between the first and second substantially transparent substrate;
- a primary seal between the spacer and the first substantially transparent substrate and between the spacer and the second substantially transparent substrate;
- an electrochromic device on at least one of the first and second substantially transparent substrates;
- and
- a bus bar associated with the electrochromic device and located in the primary seal, the bus bar camouflaged to blend in with its background.
3 more elements
An electrochromic glass structure comprising:
- a substantially transparent substrate;
- an electrochromic device disposed on the substantially transparent substrate, the electrochromic device having one or more transparent conductive layers;
- a bus bar configured to power the electrochromic device;
- and
- an opaque obscuring layer between the one or more transparent conductive layers and the substantially transparent substrate in a region proximal the bus bar.
2 more elements
An IGU comprising:
- a first pane having a first substantially transparent substrate, an electrochromic device disposed on the second substantially transparent substrate, the electrochromic device comprising a first transparent conductive layer proximal the second substantially transparent substrate, an electrochromic stack, and a second transparent conductive layer;
- a second pane having a second substantially transparent substrate;
- a spacer between the first and second panes;
- a primary sealant adhering the spacer to the first and second panes;
- a pair of bus bars on the first transparent conductive layer, nearest the first pane, the pair of bus bars located between the spacer and the first substantially transparent substrate such that the spacer blocks view of the pair of bus bars from an observer viewing through the second pane;
- and
- one or more transparent bus bars on the second transparent conductive layer.
4 more elements
An IGU or laminate comprising:
- a) an electrochromic device on at least one transparent substrate, of at least two transparent substrates of the IGU or laminate;
- b) at least one transparent bus bar configured to electrically power the electrochromic device.
