Imagine a photovoltaic cell or module that actually produces and stores energy, acting as a battery and producing power even after dark. New research into silicon-based supercapacitors at Vanderbilt University shows that it’s possible.  Supercapacitors have long been looked at as a potential alternative to batteries for energy storage, but they rem
