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.

Claims (22)

1 . 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.

2 . The electrochromic glass structure of claim 1 , further comprising another substantially transparent substrate laminated to the substantially transparent substrate.

3 . The electrochromic glass structure of claim 1 wherein the bus bar is optically unobtrusive.

4 . The electrochromic glass structure of claim 1 wherein the bus bar is located with a viewable area of the electrochromic glass structure.

5 . 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.

6 . The IGU of claim 5 , further comprising another substantially transparent substrate laminated to the substantially transparent substrate.

7 . The IGU of claim 5 wherein the bus bar is optically unobtrusive.

8 . The IGU of claim 5 wherein the bus bar is located with a viewable area of the IGU.
