Highly Absorbing, Flexible Solar Cells Created With Silicon Wire Arrays

Using arrays of long, thin silicon wires embedded in a polymer substrate, California Institute of Technology scientists have created a new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons. The solar cell uses a fraction of the expensive semiconductor materials required by conventional solar cells.

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.
