Photovoltaic cells for converting solar energy to electricity work best if they have large internal surface areas between electron-donating and electron-accepting materials to collect light-generated charge. A collaboration between Center researchers at the University of Colorado Boulder and the National Renewable Energy Laboratory has found that networks of 20 nm diameter liquid crystal filaments do this job very well.
