Claim 3:
4. A method of fabricating an electrochromic device comprising an electrochromic stack between a first and a second transparent electrically conductive layer configured to establish an electrical potential across the electrochromic stack and thereby cause optical switching of the electrochromic device, the method comprising:
(a) receiving a substrate with the first transparent electrically conductive layer disposed on a surface of the substrate;
(b) fabricating the electrochromic stack on the first transparent electrically conductive layer, wherein the electrochromic stack comprises an electrochromic layer and a counter electrode layer;
(c) forming the second transparent electrically conductive layer on the electrochromic stack;
(d) deactivating a region of the electrochromic device to form a resistive material such that the electrochromic device is substantially non-functioning in the region; and
(e) forming a bus bar on a portion of the second transparent electrically conductive layer that is over first transparent electrically conductive layer,
wherein (b) and (c) are performed without electrically isolating any portion of the first transparent electrically conductive layer before forming the second transparent electrically conductive layer,
wherein the bus bar formed over the first transparent electrically conductive layer is formed over the region.
