Does mesoporosity enhance thin film properties? A question of electrode material for electrochromism of WO3.
Replacing the commonly used indium tin oxide (ITO) with a thin metal layer as a quasi-transparent electrode leads to enhancement and acceleration of the electrochromic response of WO(3), as otherwise there is an electronic activation barrier at the interface between WO(3) and the ITO electrode, impeding fast electron transfer.
