If generated from water using renewable energy, hydrogen could serve as a carbon-zero, environmentally benign fuel to meet the needs of modern society. Photoelectrochemical cells integrate the absorption and conversion of solar energy and chemical catalysis for the generation of high value products. Tandem photoelectrochemical devices have demonstrated impressive solar-to-hydrogen conversion efficiencies but have not become economically relevant due to high production cost. Dye-sensitized solar cells, those based on a monolayer of molecular dye adsorbed to a high surface area, optically transparent semiconductor electrode, offer a possible route to realizing tandem photochemical systems for H production by water photolysis with lower overall material and processing costs. This review addresses the design and materials important to the development of tandem dye-sensitized photoelectrochemical cells for solar H production and highlights current published reports detailing systems capable of spontaneous H formation from water using only dye-sensitized interfaces for light capture.
如果利用可再生能源从水中制取,氢气可以作为一种零碳、环境友好型燃料,以满足现代社会的需求。光电化学电池将太阳能的吸收与转换和化学催化相结合,用于生成高价值产品。串联式光电化学装置已展现出令人瞩目的太阳能到氢能的转换效率,但由于生产成本高昂,尚未在经济上具有可行性。染料敏化太阳能电池是基于吸附在高表面积、光学透明半导体电极上的单层分子染料,它为实现通过光解水制取氢气的串联光化学系统提供了一条可能的途径,且总体材料和加工成本更低。本综述探讨了对于开发用于太阳能制氢的串联染料敏化光电化学电池至关重要的设计和材料,并重点介绍了当前已发表的报告,这些报告详细阐述了仅使用染料敏化界面进行光捕获就能从水中自发产生氢气的系统。
