The Joint Center for Artificial Photosynthesis (JCAP) is one of the Department of Energy Innovation Hubs. Its mission is to generate carbon-neutral fuels efficiently using only sunlight and water or carbon dioxide and sustainable materials. A number of CSD scientists participate in JCAP, working on catalysts, transformations using materials assemblies, and interfacial chemistry.
Dr. Persson studies the physics and chemistry of materials using atomistic computational methods and high-performance computing technology, particularly for clean-energy production and storage applications.
In JCAP, Dr. Persson’s research centers around photocathodes which carry out the carbon dioxide reduction reaction that are a central to the establishment of efficient, sustainable CO2 reduction. Photoelectrode architectures that include a semiconductor-liquid junction and exclude multiple buried p-n junctions are desirable for maximal efficiency and scalability of solar-fuel generation. To realize this design paradigm, new light absorbers which meet a host of design criteria must be discovered. Dr. Persson’s team will identify the most promising light absorbers for solar-fuels applications through a multi-faceted materials-discovery platform that combines high-throughput computation and experiments.
