'Invisible wires' could boost solar-cell efficiency
Vijay Narasimhan explains how he and colleagues in the Yi Cui Group at Stanford University discovered how to hide metal wires in solar cells and funnel light directly to the semiconductor below. The new technique has the potential to improve the relative efficiency of solar cells by 10 percent.
