Getting More from the Sun

Iowa State researchers led by Vikram Dalal are hoping their work with materials science and plasma chemistry will bump up the performance of solar panels by 40%–50%. The key lies in improving hydrogen bonding to the silicon in thin-film panels. Doing so could improve the efficiency of the cells by ~35% and eliminate ~15% of the drop in performance.
