Raising efficiency while lowering costs is the trend in solar as well as solid-state lighting. Researchers have been working toward this end in both areas for decades, and there are many advances to report. Researchers at the University of Texas at Austin are working on sunlight-absorbing nanoparticle inks. In the solar research arena, scientists are looking at new materials, such as cadmium telluride (CdTe) thin film, nanoparticles, optical fibers and more. First Solar of Tempe, Ariz., hit the milestone of $1 per watt in October 2009 with its CdTe technology, but, like others, the...Read full article

    efficiency
    As applied to a device or machine, the ratio of total power input to the usable power output of the device.
    thin film
    A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
