First Solar Cell Printed on Paper Achieved by MIT Scientists

Scientists at the Eni-MIT Solar Frontiers Research Center have successfully developed the first solar cells printed on paper, using a process similar to inkjet printing. Organic semiconductors in the form of carbon-based dyes were applied to paper, resulting in a solar cell with a 1.5- to 2-percent sunlight conversion efficiency rate. (Current thin-film solar cells have achieved record efficiency ...
