Abstract
Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.
Claims21
A method of manufacturing an insulated glass unit (IGU), the method comprising, in the following order:
- (1) fabricating a solid-state and inorganic electrochromic device film on a glass sheet;
- (2) fabricating the IGU using the glass sheet;
- and then
- (3) strengthening the glass sheet while in the IGU fabricated in (2);
- wherein the solid-state and inorganic electrochromic device film faces the interior volume of the IGU, and
- wherein strengthening the glass sheet comprises laminating the glass sheet with a reinforcing substrate or applying a polymeric coating to the glass sheet.
