TORONTO, June 28, 2011 — The first efficient tandem solar cell based on colloidal quantum dots (CQD) was reported at the University of Toronto, which said it may pave the way to inexpensive coatings that convert the sun's rays to electricity. "The U of T device is a stack of two light-absorbing layers — one tuned to capture the sun's visible rays, the other engineered to harvest the half of the sun's power that lies in the infrared," said Dr. Xihua Wang, lead author of a paper on a work. "We needed a breakthrough in architecting the interface between the visible and infrared junction,” said...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.
