Understanding the Exposed Area Dependent Photoelectrochemical Performance of BiVO4 Photoanodes

Abstract To enable meaningful comparisons in solar fuel production, the energy conversion efficiency of photoelectrodes must be evaluated using standardized benchmarking protocols. For solar water splitting, the photocurrent density at a defined potential in a three-electrode con...

Quantifying the Photoelectrochemically Active Surface Area for Oxygen Evolution Metal Oxide Photoelectrocatalysts

Abstract Nanostructuring is established as a photoelectrode performance enhancing route for solar-driven catalytic processes. However, it is often unclear to what extent the increase in photoelectrode physical surface area directly results in a commensurate increase in photoelect...
