New solar cell self-repairs like natural plant systems

New solar cell self-repairs like natural plant systems: "Researchers are creating a new type of solar cell designed to self-repair like natural photosynthetic systems in plants by using carbon nanotubes and DNA, an approach aimed at increasing service life and reducing cost. 'We've created artificial photosystems using optical nanomaterials to harvest solar energy that is converted to electrical power,' said Jong Hyun Choi, an assistant professor of mechanical engineering at Purdue University, West Lafayette, Ind.
