Abstract: An epitaxial p-Si(p+/p-Si)containing semiconductive high-low junction was used as photocathode in both photoelectrochemical voltaic and photoassisted hydrogen evolution cells. The conversion efficiencies were 7.4% (V2+/3+ redox couple) and 7.8% (Co-W alloy decorated) respectively. The role of high-low junction in improving conversion efficiency was disscussed.
