Total systems analysis, assembly and testing
The goal of this subtask is to develop design parameters for a complete, efficient solar fuels system.
The solar water splitting device consists of four subsystems, artificial antenna-reaction center complex, water oxidation catalyst, fuel production complex and functional nanostructured electrode. Research of Subtask 1 aims at combining the subsystems into an efficient, functional unit in the face of thermodynamic and kinetic constraints and emergent phenomena. The most challenging part of the project is to incorporate artificial mimics of photosynthesis with dye-sensitized photovoltaic technology to achieve solar-to-fuel efficiencies that surpass those of photosynthesis or single-junction PV-driven electrolysis of water. The assembly is coordinated by scientists with a broad knowledge of energy flow and control in natural systems and experience in the limitations of artificial analogs.
