1. 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;
a pair of bus bars disposed on opposing sides of the transparent substrate of the monolithic electrochromic device, one of the bus bars in electrical communication with the first transparent conductor layer and the other in electrical communication with the second transparent conductor layer; and
a powering mechanism comprising one or more wires attached to each bus bar of the pair of bus bars and one or more powering algorithms for delivering power to the pair of bus bars;
wherein the bus bars and the powering mechanism are configured to establish and maintain both of: 1) a tint gradient along the length of the electrochromic device, and, 2) a uniform tint across the monolithic electrochromic device, in the alternative,
wherein each bus bar of the pair of bus bars is electrically coupled to a pair of power leads, and
wherein the pair of bus bars is disposed on the transparent substrate.
