Electrochromic window fabrication methods
First Claim
1. A method of fabricating an electrochromic window comprising:
- i. coating a rectangular transparent substrate with an electrochromic device;
ii. edge deleting a perimeter portion, between about 5 mm and about 15 mm wide, of the electrochromic device about the perimeter of the rectangular transparent substrate;
iii. removing a portion of the electrochromic device along one edge to expose a lower transparent conducting oxide layer to form a bus bar pad expose area; and
iv. sealing the peripheral edge of the electrochromic device within the primary seal of an insulated glass unit.

Abstract
Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU'"'"'s) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.
