Electrochromic windows and method of making the same
First Claim
1. A method of making an electrochromic device comprising the steps of:
- providing an assembly including a first substrate and a second substrate spaced apart and joined by a seal to form a sealed chamber between inner surfaces of said substrates, one of said first and second substrates including an aperture extending between the outer surface of the substrate and the chamber;
filling said chamber with an electrochromic solution or an electrolytic solution through said conical-shaped aperture;
placing a plug in said aperture; and
adhering a thin plate over the plugged aperture using a UV-curable adhesive.

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. Also disclosed is the use of steel bus clips for the electrochromic device.

12. A method of making an electrochromic device comprising the steps of:
-
providing a first substrate;
adhering a first surface of a pre-formed seal gasket onto a first surface of said first substrate proximate the periphery thereof, said seal gasket having adhesive pre-applied to a second surface opposite the first surface, and having a release liner attached to the adhesive on the second surface of said seal gasket;
removing the release liner from the second surface of said seal gasket; and

23. An electrochromic device comprising:
-
a first substrate and a second substrate spaced apart and joined by a seal to form a sealed chamber between inner surfaces of said substrates, said substrates being positioned to have at least a first edge aligned with the first edge of the other substrate;
a first electrode disposed on the inner surface of said first substrate;
a second electrode disposed on the inner surface of said second substrate, said first and second electrodes being electrically isolated from one another;
