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 H2 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 H2 production and highlights current published reports detailing systems capable of spontaneous H2 formation from water using only dye-sensitized interfaces for light capture.

使用串联染料敏化光电化学电池从水中可持续制氢

如果使用可再生能源从水中产生氢，则氢可作为零碳，对环境无害的燃料，以满足现代社会的需求。光电化学电池整合了太阳能的吸收和转化以及化学催化作用，以生成高价值的产品。串联光电化学装置已经显示出令人印象深刻的太阳能到氢的转换效率，但是由于高生产成本而在经济上没有意义。染料敏化太阳能电池是基于分子染料单分子层吸附到高表面积的光学透明半导体电极而构成的，它为实现通过水光解法生产H2的串联光化学系统提供了一条可能的途径，同时降低了总体材料和处理成本。
