Solar energy has yet to get an order of magnitude even cheaper .Researchers claim a breakthrough in polymer solar cells; cheap & easy to manufacture solar cells that can be printed on rolls of plastic

Chinese scientists build ‘ultra-stable’ polymer solar cell with 19.1% efficiency

The polymer solar cell is able to retain 97% of its performance after 2,000 hours in air. By blending small-molecule acceptors into polymeric matrices, the research team improved molecular packing, en...
