Journal ArticleDOI
Efficient solar water splitting by enhanced charge separation in a bismuth vanadate-silicon tandem photoelectrode
Fatwa F. Abdi,Lihao Han,Arno H. M. Smets,Miro Zeman,Bernard Dam,Roel van de Krol,Roel van de Krol +6 more
TL;DR: By combining this state-of-the-art photoanode with an earth-abundant cobalt phosphate water-oxidation catalyst and a double- or single-junction amorphous Si solar cell in a tandem configuration, stable short-circuit water-splitting photocurrents of ~4 and 3 mA cm(-2) are achieved under 1 sun illumination.
Journal ArticleDOI
Nature and Light Dependence of Bulk Recombination in Co-Pi-Catalyzed BiVO4 Photoanodes
Fatwa F. Abdi,Roel van de Krol +1 more
TL;DR: In this paper, the authors confirm recent reports that cobalt phosphate (Co-Pi) is an efficient water oxidation catalyst for BiVO4 and report an AM1.5 photocurrent of 1.7 mA/cm2 at 1.23 V vs RHE for 100 nm spray-deposited, compact, and undoped biVO4 films with an optimized Co-Pi film thickness of 30 nm.
Journal ArticleDOI
The Origin of Slow Carrier Transport in BiVO4 Thin Film Photoanodes: A Time-Resolved Microwave Conductivity Study
TL;DR: In this paper, the authors unraveled the origin of the poor carrier transport properties of BiVO4, a promising metal oxide photoanode for solar water splitting, and showed that Tungsten doping is strongly decreasing the carrier mobility by introducing intermediate-depth donor defects as carrier traps.
Journal ArticleDOI
Photocurrent of BiVO4 is limited by surface recombination, not surface catalysis
TL;DR: The main role of a cobalt phosphate catalyst on BiVO4 is to improve the photocurrent by passivating the surface and suppressing recombination.
Journal ArticleDOI
Efficient BiVO4 Thin Film Photoanodes Modified with Cobalt Phosphate Catalyst and W‐doping
TL;DR: In this article, Bismuth vanadate (BiVO4) thin film photoanodes for light-induced water oxidation are deposited by a low-cost and scalable spray pyrolysis method.
