The Joint Center for Artificial Photosynthesis (JCAP) is the nation’s largest research program dedicated to the development of an artificial solar-fuel generation technology. Established in 2010 as a U.S. Department of Energy (DOE) Energy Innovation Hub, JCAP aims to find a cost-effective method to produce fuels using only sunlight, water, and carbon dioxide as inputs.

How Can Theory Help with Rapid Screening of Promising Photocatalysts in Solvent?

JCAP scientists are developing novel theoretical methods to predict the effect that solvents have on material properties — and consequently the photoelectrochemical performance — inside solar-fuels generators.  More
