Solar-driven photoelectrochemical (PEC) water splitting into hydrogen fuel is a promising avenue for renewable energy conversion to overcome energy crises and environmental concerns. Earth-abundant Si semiconductors with excellent light-harvesting capabilities are suitable photocathode candidates for the PEC hydrogen evolution reaction (HER), but suffer from intrinsic instability and sluggish kinetics. Extensive studies have demonstrated that surface/interface engineering can serve as an effective strategy for fabricating Si-based photocathodes with sufficient surface catalytic activity and facile interfacial carrier transport. In this Review, we first briefly introduce the current status of PEC HER using Si-based photocathodes and summarize their fabrication techniques. Subsequently, a systematic overview of recent achievements in surface/interface engineering of Si-based photocathodes is presented to illustrate their distinct roles in boosting the PEC-HER performance. Finally, the perspective views regarding the further development of practical Si-based photocathodes are discussed. This Review aims to promote an in-depth understanding and technical evaluation of surface/interface engineering strategies for efficient Si-based PEC HER.

用于高效析氢的硅基光电阴极的表面/界面工程

太阳能驱动的光电化学 (PEC) 水分解成氢燃料是可再生能源转换以克服能源危机和环境问题的有前途的途径。地球上储量丰富的硅半导体具有出色的光捕获能力，是 PEC 析氢反应 (HER) 的合适光电阴极候选材料，但存在固有的不稳定性和动力学缓慢的问题。大量研究表明，表面/界面工程可以作为制造具有足够表面催化活性和容易的界面载流子传输的硅基光电阴极的有效策略。在这篇综述中，我们首先简要介绍了使用硅基光电阴极的 PEC HER 的现状，并总结了它们的制造技术。随后，系统地概述了硅基光电阴极表面/界面工程的最新成就，以说明它们在提高 PEC-HER 性能方面的独特作用。最后，讨论了关于实用硅基光电阴极进一步发展的前景。本综述旨在促进对高效硅基 PEC HER 的表面/界面工程策略的深入理解和技术评估。
