The Sun generates enough energy to power the Earth. However, solar energy should be stored into chemical energy to be conveniently used due to its low energy density and discontinuous radiation. In the last several years, photocatalysis and photoelectrochemistry for solar fuels (such as hydrogen, methanol, and methane) have reattracted more and more governments’ and people’s interest from all over the world and become a very hot topic. If we utilize the abundant solar energy to convert CO₂ into hydrocarbon fuels especially, it would address the problems of global climate change and solar energy storage at the same time. Recently, different new materials and ideas have been proposed and steady scientific progress has been done. However, a high-efficiency, stable, and low-cost system for solar fuels is still a key challenge. We believe that the final target can be obtained only when researchers from different fields, including chemistry, physics, materials sciences, and Engineering, work together. This special issue provides a platform and an opportunity to promote interaction and information exchange between researchers from different fields and would further expand the interest and progress in this area.

We invite investigators to contribute original research articles as well as review articles to this special issue. Potential topics include, but are not limited to:

• New light-capture materials, including molecular, polymer, and inorganic semiconductor
• Homo- or heterogeneous photocatalysis for solar fuels
• Photoelectrochemical cells for solar fuels
• Photostability and degradation mechanism
• Simulation theory
