Abstract
Thin-film devices, for example, multi-zone electrochromic windows, and methods of manufacturing are described. In certain cases, a multi-zone electrochromic window comprises a monolithic EC device on a transparent substrate and two or more tinting zones, wherein the tinting zones are configured for independent operation.
Claims21
An electrochromic window comprising:
- a monolithic electrochromic device disposed on a transparent substrate, and comprising a first transparent conductor layer, a second transparent conductor layer, and one or more material layers sandwiched between the first and second transparent conductor layers;
- and
- a powering mechanism comprising two or more power leads in electrical communication with the first and second transparent conductor layers via one or more bus bars disposed on each of the first and second transparent conductor layers and along the length of the monolithic electrochromic device;
- wherein the monolithic electrochromic device is configured to both maintain a tint gradient along its length and maintain a uniform tint across its area, alternatively, only via the powering mechanism and/or the one or more bus bars, and
- wherein the two or more power leads comprise a pair of power leads electrically coupled to at least one bus bar of the one or more bus bars.

An electrochromic window comprising:
- an electrochromic device disposed on a transparent substrate, and comprising a first transparent conductor layer, a second transparent conductor layer, and one or more material layers sandwiched between the first and second transparent conductor layers;
- and
- a bus bar disposed on and in electrical communication with one of the first transparent conductor layer and the second transparent conductor layer, the bus bar electrically coupled to a pair of power leads;
- and
- a powering mechanism comprising one or more powering algorithms configured to control power delivered to the pair of power leads;
- wherein the bus bar and the powering mechanism are configured to establish and maintain either a tint gradient along the length of the electrochromic window, or, a uniform tint across the electrochromic device.
