ScienceDaily: Environmentally compatible production methods for organic solar cells from novel materials are in the focus of "MatHero." The new project coordinated by Karlsruhe Institute of Technology (KIT) aims at making organic photovoltaics competitive to their inorganic counterparts by enhancing the efficiency of organic solar cells, reducing their production costs and increasing their life-time. "Green" processes for materials synthesis and coating play a key role. "MatHero" is funded by the European Commission...
