Abstract
Methods are provided for fabricating electrochromic devices that mitigate formation of short circuits under a top bus bar without predetermining where top bus bars will be applied on the device. Devices fabricated using such methods may be deactivated under the top bus bar, or may include active material under the top bus bar. Methods of fabricating devices with active material under a top bus bar include depositing a modified top bus bar, fabricating self-healing layers in the electrochromic device, and modifying a top transparent conductive layer of the device prior to applying bus bars.
Claims (18)
1. A method of manufacturing an electrochromic device comprising an electrochromic stack between a first and a second transparent electronically conductive layer configured to deliver potential over surfaces of the electrochromic stack and thereby cause optical switching of the electrochromic device, the method of manufacturing comprising:
(a) fabricating the electrochromic stack on a glass substrate without pre-patterning in a first facility;
(b) shipping the glass substrate including the electrochromic stack to a second facility; and
(c) performing post-processing in the second facility,
wherein a protective layer is deposited over the second transparent electronically conductive layer and the electrochromic stack in the first facility, wherein the protective layer is a hermetic top coat,
wherein (c) comprises removing the deposited protective layer.
2. The method of claim 1 , wherein the second transparent electronically conductive layer is formed on the electrochromic stack.
3. The method of claim 1 , wherein the protective layer is deposited on the second transparent electronically conductive layer.
4. The method of claim 1 , wherein the protective layer is deposited on the electrochromic stack.
5. The method of claim 1 , wherein the protective layer is removed after shipping to the second facility and prior to performing the post-processing in the second facility.
6. The method of claim 1 , wherein the glass substrate is deposited with the first transparent electronically conductive layer.
7. The method of claim 6 , wherein the electrochromic stack is fabricated on the first transparent electronically conductive layer.
8. The method of claim 1 , wherein the electrochromic stack comprises an electrochromic layer and a counter electrode layer.
9. The method of claim 1 , further comprising: (d) fabricating an insulated glass unit.
10. The method of claim 1 , wherein (c) comprises applying bus bars.
11. The method of claim 1 , wherein (c) comprises cutting, laminating, and fabricating an insulated glass unit.
12. The method of claim 1 , wherein (c) comprises laser patterning of the electrochromic stack.
13. The method of claim 1 , wherein the protective layer is made of material selected from the group consisting of parylenes, silicon-based encapsulants, epoxy-based encapsulants, oxide-polymer multilayers, acrylic materials, ceramic materials, adhesive materials, vinyl materials, and combinations thereof.
