Transparent Material Harvests Light

Facebook X LinkedIn Email
UPTON, N.Y., Nov. 5, 2010 — Scientists at Brookhaven and Los Alamos national laboratories have fabricated transparent thin films capable of absorbing light and generating electric charge over a relatively large area. Described in the journal Chemistry of Materials, the material could be used to develop transparent solar panels or even windows that absorb solar energy to generate electricity. It consists of a semiconducting polymer doped with carbon-rich fullerenes. Under carefully controlled conditions, it self-assembles to form a reproducible pattern of micron-sized hexagon-shaped cells over a relatively...Read full article

    Glossary
    fullerenes
    Molecules composed entirely of carbon, in the form of a hollow sphere, ellipsoid or tube. Also called buckyballs. Cylindrical fullerenes are called carbon nanotubes or buckytubes.
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    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.
    nanotechnology
    The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
