摘要： 本文采用p+/p-Si作为光阴极进行了光电化学电池和光助析氢电池的研究,光转换效率分别达到了7.4%(V2+/3+电对)和7.8%(Co—W修饰),并讨论了导致高效率的原因,强调了高-低结对于改善半导体光电极性能的重要性。

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.
