In a remarkable feat, scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin film solar cells on flexible polymer foils with a new record efficiency of 20.4 percent for converting sunlight into electricity. The cells are based on CIGS semiconducting material known for its potential to provide cost-effective solar electricity. The technology is currently awaiting scale-up for industrial applications.
