National Renewable Energy Laboratory (NREL) Research Scientist Bryon Larson, as part of an international research team, achieved a record-breaking 18.07% power conversion efficiency from an organic photovoltaic (OPV) solar cell – or as such materials are better known: Plastic.    Historically, OPV cells have mostly improved through an iterative process.    However, Larson and his collaborators have hit upon an “aha!” moment with a new design strategy that simultaneously improves the cell...
