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.
Claims8
An electrochromic glass structure, comprising:
- a substantially transparent substrate;
- an electrochromic device disposed on the substantially transparent substrate;
- and
- a bus bar configured to power the electrochromic device;
- wherein the bus bar is disposed in a trench in the substantially transparent substrate;
- wherein the bus bar comprises a transparent material;
- and
- wherein the bus bar includes carbon or silver nanostructures.
5 more elements
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 disposed on the first substantially transparent substrate;
- and
- a bus bar configured to power the electrochromic device;
- wherein the bus bar is disposed in a trench in the substantially transparent substrate;
- wherein the bus bar comprises a transparent material;
- and
- wherein the bus bar includes carbon or silver nanostructures.
