Electrochromic properties of atmospheric CVD MoO3 and MoO3-WO3 films and their application in electrochromic devices

It was found that the CVD deposited MoO3 and Mo0.07W0.93O3 thin films performed well as electrodes in electrochromic devices. We made devices based on Mo0.07W0.93O3/LiClO4 + propylene carbonate + polyvinyl alcohol + PVA/SnO2:Sb. The devices exhibited good cyclic reversibility (colored/bleached state) and good coloration efficiencies. We measured a transmittance change (600 nm) of 48.4% switching to 17.4% for our best device.
