JCAP

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.

  • Electrochemical scanning probe droplet cell for high-throughput evaluation of catalysts and light absorbers.
  • JCAP staff scientist Ian Sharp operating an amplified Ti:Sapphire laser for time-resolved photoluminescence measurements of light absorbers.
  • Color enhanced scanning electron microscope image of a silicon column and pit patterned by electron-beam lithography.
  • A first generation JCAP prototype of a tileable solar-fuel generating module.
  • JCAP graduate students Eric Verlage and Prineha Narang operating a spectroscopic ellipsometer for band-gap measurements of light absorbers.

Direct Observation of a Semiconductor/Liquid Junction by Operando X-Ray Photoelectron Spectroscopy (XPS)

Operando XPS is used to directly measure the positions of the electronic states of the electrode and the electrolyte.  More
