ELECTROCHROMIC WINDOWS AND METHOD OF MAKING THE SAME
First Claim
1. A method of making an electro-optic device comprising the steps of:
- providing a first substrate;
providing a seal around the perimeter of said first substrate;
aligning a second substrate with said first substrate and securing said second substrate to said first substrate to form a subassembly such that said first and second substrates are maintained in spaced relation to one another and with said seal defining a volume therebetween, wherein said subassembly includes only one fill hole, and wherein said fill hole is formed through one of said first and second substrates;
filling said volume between the first surfaces of said first and second substrates with a solution through said fill hole to form the electro-optic device; and
sealing said fill hole.

Abstract
An electrochromic window assembly is disclosed that includes a first substrate and a second substrate that is maintained in a parallel and spaced relation from the first substrate by means of a window frame and spacer. The window assembly further includes an electrochromic device mounted within the airtight chamber formed between the first and second substrates. Electrochromic device 22 may be mounted so as to provide an air chamber between first substrate 12, which is the external substrate, and electrochromic device 22. At least one of the chambers formed between substrates 12 and 14 and electrochromic device 22 may be filled with an insulating gas such as argon. Also disclosed are novel methods for manufacture of an electrochromic device for incorporation into such a window assembly. A novel electrochromic device is also disclosed having electrical bus clips secured about the entire periphery of the electrochromic device.
