Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices
