The present invention generally relates to electrochromic (EC) devices, such as used in electrochromic windows (ECWs), and their manufacture. The EC devices may comprise a transparent substrate; a first transparent conductive layer; a doped coloration layer, wherein the coloration layer dopants provide structural stability to the arrangement of atoms in the coloration layer; an electrolyte layer; a doped anode layer over said electrolyte layer, wherein the anode layer dopant provides increased electrically conductivity in the doped anode layer; and a second transparent conductive layer. A method of fabricating an electrochromic device may comprise depositing on a substrate, in sequence, a first transparent conductive layer, a doped coloration layer, an electrolyte layer, a doped anode layer, and a second transparent conductive layer, wherein at least one of the doped coloration layer, the electrolyte layer and the doped anode layer is sputter deposited using a combinatorial plasma deposition process.
