NREL Breakthrough Could Spawn Cheaper, More Efficient Solar Cells

September 13, 2010

A special etching process developed at the National Renewable Energy Laboratory (NREL) makes silicon wafers darker, and thus able to absorb almost all of the solar spectra that reach the surface. This innovation is expected to lead to solar cells that cost less and are more efficient than the ones used on rooftops and in solar arrays today.
