1. An electrochromic window comprising:
an electrochromic device disposed on a transparent substrate, the electrochromic device comprising a first transparent conductive layer and a second transparent conductive layer;
bus bars located along opposing edges of the electrochromic device, wherein at least a first bus bar of the bus bars is in electrical communication with the first transparent conductive oxide layer and at least a second bus bar of the bus bars is in electrical communication with the second transparent conductive oxide layer;
wherein the bus bars are configured to establish and maintain, when the electrochromic device is energized, a tint gradient across the electrochromic window,
wherein the electrochromic device has at most four bus bars, and
wherein, during operation, voltage is applied at more than one point along each of the first bus bar and/or the second bus bar.
