The conversion of solar energy into hydrogen through photoelectrochemical (PEC) water splitting is an attractive way to store renewable energy. Despite the intriguing concept of solar hydrogen production, efficient PEC devices based on earth-abundant semiconductors should be realized to compete economically with conventional steam reforming processes. Herein, recent milestones in photocathode development for PEC water splitting, particularly in earth-abundant semiconductors, in terms of new techniques for enhancing performance, as well as theoretical aspects, are highlighted. In addition, recent research into newly emerging low-cost p-type semiconductors in the PEC field, such as Cu BaSn(S,Se) and Sb Se , are scrutinized and the advantages and disadvantages of each material assessed.
通过光电化学（PEC）水分解将太阳能转化为氢气是一种极具吸引力的可再生能源存储方式。尽管太阳能制氢的概念很吸引人，但要在经济上与传统的蒸汽重整工艺竞争，就需要实现基于储量丰富的半导体的高效PEC装置。本文重点介绍了PEC水分解光阴极开发方面的最新进展，特别是在储量丰富的半导体领域，包括提高性能的新技术以及理论方面。此外，还对PEC领域新出现的低成本p型半导体，如CuBaSn(S,Se)和SbSe进行了详细研究，并评估了每种材料的优缺点。
