Solar Power Goes Viral

Facebook X LinkedIn Email
CAMBRIDGE, Mass., May 3, 2011 — A genetically modified virus is being used to produce structures that improve solar cell efficiency by nearly one-third. In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to produce an electric current. The new MIT research is based on findings that carbon nanotubes — microscopic, hollow cylinders of pure carbon — can enhance the efficiency of electron collection from a solar cell's surface. Previous attempts to use the nanotubes, however, had been thwarted by two problems. First, the making of carbon...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
