Physicists develop approach to increase performance of solar energy

Experimental condensed matter physicists in the Department of Physics at the University of Oklahoma have developed an approach to circumvent a major loss process that currently limits the efficiency of commercial solar cells. Members of the Photovoltaic Materials and Devices Group, led by OU associate professor in the Homer L. Dodge Department of Physics and Astronomy, Ian Sellers, along with theorists at Arizona State University, led by David K. Ferry, have demonstrated a breakthrough toward the development of a hot carrier solar cell.
