Abstract

We demonstrated highly efficient solar hydrogen generation via water splitting by photovoltaic-photoelectrochemical (PV-PEC) tandem device based on GaAs/InGaAsP (PV cell) and WO 3 /BiVO 4 core/shell nanorods (PEC cell). We utilized extremely thin absorber (ETA) concept to design the WO 3 /BiVO 4 core/shell heterojunction nanorods and obtained the highest efficiencies of generation, separation and transfer of the photoinduced charge carriers that are possible for the WO 3 /BiVO 4 material combination. The PV-PEC tandem shows stable water splitting photocurrent of 6.56mA&cm%2 under standard AM1.5G solar light that corresponds to the record solar-to-hydrogen (STH) conversion efficiency of 8.1%.
