Turning Light Into an Electrical Current Using a Golden Nanoscale System

University of Pennsylvania material scientists have demonstrated the transduction of optical radiation to electrical current in a molecular circuit. The array of nano-sized molecules of gold respond to electromagnetic waves by creating surface plasmons that induce and project electrical current across molecules - similar to that of photovoltaic solar cells.
