ELECTROCHROMIC WINDOW FABRICATION METHODS

摘要

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.

主权项

1. An electrochromic pane comprising:
(a) an all solid state and inorganic electrochromic device disposed on a glass sheet, wherein the electrochromic device comprises (i) a first transparent conducting oxide layer proximate the glass sheet, (ii) a second transparent conducting oxide layer, and (iii) an electrochromic stack between the first and second transparent conducting oxide layers; and (b) at least one non-penetrating bus bar attached to an outer surface of the second transparent conductive oxide layer.
