Abstract
An apparatus can include an electrochromic device. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded state and maintained at continuously graded transmission state. An apparatus can include an active stack with a first transparent conductive layer, a second transparent conductive layer, an anodic electrochemical layer between the first and the second transparent conductive layers, and a cathodic electrochemical layer between the first and the second transparent conductive layers. The apparatus can further include a first bus bar electrically coupled to the first transparent conductive layer, a second bus bar electrically coupled to the second transparent conductive layer, where the second bus bar is generally non-parallel to the first bus bar, and a third bus bar electrically coupled to the first transparent conductive layer, where the third bus bar is generally parallel to the first bus bar.
