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.

JCAP Stabilizes Common Semiconductors for Solar Fuel Generation

Researchers in JCAP have developed an approach to stabilize semiconductors in aqueous electrolytes. By depositing thick layers of titanium dioxide and nickel onto semiconductor surfaces, the researchers demonstrated that common semiconductors such as silicon and gallium arsenide can withstand corrosion for more than 100 hours under actual operating conditions.
