Solar company Konarka has announced that it successfully developed a new process to manufacture solar cells that could lead to a range of new solar-powered products and applications. The solar cells are made without silicon and are manufactured into a thin, light film via an inkjet printer, which means they don’t need to be born in a clean room like traditional silicon cells. One drawback to the new cells is their efficiency: while regular silicon solar cells achieve efficiencies of up to 20 percent, the new cells are only 5 percent efficient, but Konarka says they’re likely to be less expensive and much more dynamic. They can be incorporated into plastics and come in a range of different colors, including transparent.
