Indium Phosphide nanowires were grown and utilized as a light absorbing photocathode for solar-driven water splitting.
Significance and Impact
An improved photocathode boosted the solar to fuel efficiency of integrated photoelectrochemical (PEC) cells.
- A new growth of Wurtzite-phase Indium Phosphide nanowires was developed on multiple substrates
- Indium Phosphide photocathodes offer enhanced performance over silicon
- In Z-scheme bio-inspired configuration, Indium Phosphide photocathode was combined with a Bismuth Vanadate photoanode to drive unassisted water splitting using sunlight
