Featured Research: Valley Photovoltaics: Towards the Realization of Ultra-High Efficiency Solar Cells

Experimental condensed matter physicists in the Department of Physics at OU have developed an approach to circumvent a major loss process that currently limits commercial solar cells to conversion efficiencies less than 30 %. In this new approach, recently published in the journal Nature Energy, members of the Photovoltaic Materials & Devices Group led by Dr. Ian Sellers along with theorists at Arizona State University (David K. Ferry), have demonstrated…
