With its "Solar Feed-In Tarriff" program, Gainesville is a national leader in getting utility customers to turn to the power of the sun.  But solar power is a long ways away from being an efficient way of generating electricity.
     That is the challenge taken on by researchers at the University of Florida, who have demonstrated an important leap forward in making solar power generation much more efficient.  In the Innovation Technology interview, Art Hebard, Ph.D., Distinguished Professor of Physics at UF, explains to TV20's David Snyder what "graphene" solar cells are, and what can be applied to them to make them more efficient.
