The use of sunlight to synthesize useful chemicals such as H2 and hydrocarbon fuels from components of air (water and CO2) has progressed rapidly due to the strong international effort to identify materials and device architectures that improve efficiency and stability. The targets are challenging: a solar fuels generation system must return at least as much chemical energy as the total energy required to fabricate and operate it, and last for a decade or more. Success requires addressing corrosion, membranes properties, integrated semiconductor/catalyst systems and performance under natural conditions involving large temperature swings and diurnal operation. In this talk I will describe studies conducted in JCAP directed toward achieving these targets. Considerations for solar water splitting and CO2 reduction systems will be compared.
