Scientists at the Massachusetts Institute of Technology havedeveloped a new technology that allows solar cells to be coated onpaper. The printed solar cells are still in the research phase and might be years away from being commercialized. The technique involves thecoating of organic semiconductor material on paper using a processsimilar to an inkjet printer.
The solar cells that are developed using carbon-based dyes are about 1.5 percent to 2 percent efficient in converting light intoelectricity, but the cost of manufacturing the cells is less. MIT isfocusing much of its effort on quantum dots, which can prove beneficialin energy conversion.
