NREL Achieves 18.2% Efficient Nano Solar Cell

RSSfeed

Using a chemical nano-porous etching process, the National Renewable Energy Laboratory (NREL) was able to create an antireflective surface on silicon PV cells without using additional antireflection coating. The method could reduce the cost of adding anti-reflective layers to crystalline silicon-based photovoltaics. Researchers at the laboratory, including Jihun Oh, Hao-Chih Yuan, and Howard Branz developed a nanostructured surface for black...
