Don’t just think plastics are insulators. Two Nobel prizes were won by showing they can be semiconductors. That celebrated research opened the door to polymer-based solar cells. They are made in a lab from common elements, using processes established decades ago for ordinary household items like plastic wrap. A design strategy breakthrough led by NREL has now created an organic photovoltaic (OPV) solar cell with a record-breaking 18.07% power … [Read more...]
