Transition 2 Step

For 5 years, BRT has talked about solar in terms of why thin film flexible tech, easily manufactured and able to produce a lot of juice from sunlight, is required before solar can finally take off. Well, said tech has arrived so America, pucker up and dump fossil fuels now.

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.
