Black Silicon Solar Cell Hits 18.2% Efficiency, Should Help to Reduce Costs

Black-silicon solar cells with 18.2% efficiency have been created by researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). These don’t need extra anti-reflection layers (like typical solar cells do), which should help to significantly lower the cost of solar energy. The specially designed nanostructured surface ensures … [continued]
