Abstract
An electrochromic device includes an optically active layer having an optical property that can be altered by application of electrical power to the optically active layer and a conductive structure that is configured to supply the electrical power to the optically active layer. The conductive structure includes patterned conductive elements that cooperate with the optically active layer to define electrochromic cells.
