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.
Determining Efficiencies of Solar-
JCAP scientists have developed a model to determine the theoretical efficiencies for water-splitting solar-fuel generators. Using the model, the researchers identified the ideal parameters, including the optimal component dimensions and light-absorber properties, needed to maximize solar-fuel production efficiency. More
Evaluating the Energy Balance for a Water-Splitting System
An analysis by JCAP researchers has demonstrated that a solar-driven water-splitting device can produce more energy over its lifetime than is required to manufacture the device. The researchers used a life-cycle assessment approach to determine the primary net energy balance for various photoelectrochemical systems operating under a range of assumptions. More
