An electrochromic device is disclosed. The electrochromic device can include a stack of layers. The stack of layers can include a first transparent conductive layer on a substrate, a second transparent conductive layer, a cathodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer, and an anodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer. The stack of layers can be patterned. In one embodiment, the pattern can be parallel to a voltage gradient of the electrochromic device. In another embodiment, the pattern can extend through all layers of the stack of layers of the electrochromic device.
