Electrical Contact Technique For Electrochromic Windows
First Claim
1. A window assembly, comprising:
- a first conductive material layer formed on a substrate, the first conductive material layer comprising at least two zones that are each electrically isolated from each other;
an electrochromic stack formed on a first selected zone of the first conductive material layer to overlap at least an edge of a second selected zone of the first conductive material layer;
a second conductive material layer formed on at least a portion of the electrochromic stack to overlap at least an edge of the second selected zone of the first conductive material layer;
a first bus bar formed on the second selected zone of the conductive material layer, the first bus bar comprising a position that will be within a sealed volume of the window assembly; and
a second bus bar formed on the first selected zone, the second bus bar comprising a position that will be outside the seal volume of the window assembly.

Abstract
A window assembly comprises a first conductive material layer, an electrochromic stack, a second conductive material layer and a seal. The first conductive material layer is formed on a substrate and comprises at least two zones electrically isolated from each other. The electrochromic stack is formed on a first selected zone of the first conductive material layer to overlap an edge of a second selected zone of the first conductive material layer. The second conductive material layer is formed on the electrochromic stack to overlap an edge of the second selected zone. A first bus bar is formed on the second selected zone to be within a sealed volume of the window assembly. A second bus bar is formed on the first selected zone to be outside the seal volume of the window assembly. The seal defines the sealed volume of the window assembly and seals the window assembly.
