An electrochemical device and method of forming said device is disclosed. The method can include providing a substrate and stack overlying the substrate. The stack can include a first transparent conductive layer over the substrate, a cathodic electrochemical layer over the first transparent conductive layer, an anodic electrochemical layer over the electrochromic layer, and a second transparent conductive layer overlying the anodic electrochemical layer. The method can include depositing an insulating layer over the stack and determining a first pattern for the second transparent conductive layer. The first pattern can include a first region and a second region. The first region and the second region can be the same material. The method can include patterning the first region of the second transparent conductive layer without removing the material from the first region. The first region can have a first resistivity and the second region can have a second resistivity.

Made-to-stock patterned transparent conductive layer

A method of operating an electrochromic device comprising: coupling a logic device to the electrochromic device; applying a voltage to the electrochromic device; receiving a current from the electrochromic device in response to the provided voltage; and with the logic device, determining an exact operating condition of the electrochromic device from the received current. A method of operating a plurality of electrochromic devices comprising: adjusting a frequency of voltage applied to the plurality of electrochromic devices, wherein each of the plurality of electrochromic devices is adjusted by a different frequency; measuring a duration of time required to change tint states of each of the electrochromic devices; and identifying a location of each of the plurality of electrochromic devices in response to the measured duration of time required to change the tint states of each of the electrochromic device.
