A method of fabricating an electrochromic stack, the method comprising:
- forming a cathodically coloring layer comprising a cathodically coloring electrochromic material;
- and
- forming an anodically coloring layer comprising an inorganic anodically coloring electrochromic material comprising one or more halogens, the anodically coloring layer optionally comprising one or more additives,
- wherein the inorganic anodically coloring electrochromic material comprises at least one metal selected from the group consisting of chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), rhodium (Rh), ruthenium (Ru), vanadium (V), and iridium (Ir), and
- wherein the optional one or more additives comprises a material selected from the group consisting of silver (Ag), arsenic (As), gold (Au), boron (B), cadmium (Cd), cesium (Cs), copper (Cu), europium (Eu), gallium (Ga), gadolinium (Gd), germanium (Ge), mercury (Hg), osmium (Os), lead (Pb), palladium (Pd), promethium (Pm), polonium (Po), platinum (Pt), radium (Ra), rubidium (Rb), terbium (Tb), technetium (Tc), thorium (Th), thallium (Tl), tungsten (W), and combinations thereof.
