Triangle researchers find possible solution to solar energy problem

CHAPEL HILL — A team of researchers led by a UNC-Chapel Hill chemistry professor has discovered a potential solution to one of the fundamental problems of generating large amounts of energy from the sun’s rays: how to store some of the power so it’s available at night. The scientists, who also include researchers from N.C. State University, found a new way to use solar energy to split molecules of water into its atomic-level components: oxygen and hydrogen. The hydrogen can then be...
