Abstract: An electrochromic (EC) device includes a first substrate, a second substrate, a transparent first conductor disposed between the first and second substrates, a transparent second conductor disposed between the first and second substrates, a working electrode disposed between the first and second conductors, a counter electrode disposed between the working electrode and the second conductor, and an electrolyte disposed between the working and counter electrodes. At least one of the first or second conductors is a multipart conductor which includes a transparent first conductive film, a first contact strip extending lengthwise in a first direction which is perpendicular to a second direction, along a first side of the EC device, and first conductive lines extending from the first contact strip toward an opposing second side of the EC device. The multipart conductor has a lower effective sheet resistance in the second direction than in the first direction.
