可再生燃料发电对于低碳足迹经济至关重要。因此，在过去的五十年中，已经致力于提高太阳能燃料发电装置的性能。具体而言，光电化学电池的太阳能转化为氢的效率已经朝着其基本极限稳步发展，并且在CO2还原系统中对有价值的产物的法拉第效率已经显著增加。然而，为了将太阳能燃料转化为可行的技术，仍然存在许多必须克服的科学和工程挑战。在电极和器件层面，必须显著提高转化效率、稳定性和产物选择性。同时，在扩展设备和系统时必须保持这些性能指标，同时保持可接受的成本和碳足迹。该路线图调查了这一奋进的不同方面：系统基准测试，设备缩放，光电极设计的各种方法，材料发现和催化。路线图中的每一部分都侧重于一个主题，讨论最新技术水平、关键挑战以及满足这些挑战所需的进步。该路线图可以作为研究人员和资助机构的指南，突出该领域最紧迫的需求。
Renewable fuel generation is essential for a low carbon footprint economy. Thus, over the last five decades, a significant effort has been dedicated towards increasing the performance of solar fuels generating devices. Specifically, the solar to hydrogen efficiency of photoelectrochemical cells has progressed steadily towards its fundamental limit, and the faradaic efficiency towards valuable products in CO2 reduction systems has increased dramatically. However, there are still numerous scientific and engineering challenges that must be overcame in order to turn solar fuels into a viable technology. At the electrode and device level, the conversion efficiency, stability and products selectivity must be increased significantly. Meanwhile, these performance metrics must be maintained when scaling up devices and systems while maintaining an acceptable cost and carbon footprint. This roadmap surveys different aspects of this endeavor: system benchmarking, device scaling, various approaches for photoelectrodes design, materials discovery, and catalysis. Each of the sections in the roadmap focuses on a single topic, discussing the state of the art, the key challenges and advancements required to meet them. The roadmap can be used as a guide for researchers and funding agencies highlighting the most pressing needs of the field.
