Kevin Makice on 25 Apr 11In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to produce an electric current. The new MIT research, published online this week in the journal Nature Nanotechnology, is based on findings that carbon nanotubes - microscopic, hollow cylinders of pure carbon - can enhance the efficiency of electron collection from a solar cell's surface.
