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.

This disclosure describes insulated glass units (IGUs) that incorporate electrochromic devices. More specifically, this disclosure focuses on different configurations available for providing an electrical connection to the interior region of an IGU. In many cases, an IGU includes two panes separated by a spacer. The spacer defines an interior region of the IGU and an exterior region of the IGU. Often, the electrochromic device positioned on the pane does not extend past the spacer, and some electrical connection must be provided to supply power from the exterior of the IGU to the electrochromic device on the interior of the IGU. In some embodiments, the spacer includes one or more holes (e.g, channels, mouse holes, other holes, etc.) through which an electrical connection (e.g., wires, busbar leads, etc.) may pass to provide power to the electrochromic device.

A window unit (e.g., insulating glass (IG) window unit) is designed to reduce bird collisions therewith. The window unit may include two or three substrates and at least one of the substrates supports an ultraviolet (UV) reflecting coating. The UV reflecting coating may be patterned by a laser (e.g., femto laser) which is used to either entirely or partially remove (e.g., via laser ablation) a portion of the coating in a pattern, so that after patterning by the laser the patterned coating is either not provided across the entirety of the window unit and/or is non-uniform in UV reflection across the window unit so that the UV reflection differs across different areas of the window thereby making the window unit more visible to birds which can see UV radiation and detect that pattern.
