Researchers from the University of Pennsylvania have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.

Dawn Bonnell, Penn’s vice provost for research and Trustee Professor of Materials Science and Engineering in the School of Engineering and Applied Science, led the work, along with David Conklin, a doctoral student. The study involved a collaboration among additional Penn researchers, through theNano/Bio Interface Center, as well as a partnership with the lab of Michael J. Therien of Duke University.

“We’re excited to have found a process that is much more efficient than conventional photoconduction,” Bonnell said. “Using such an approach could make solar energy harvesting and optoelectronic devices much better.”  Read More
