Material grabs more sun: "Most photovoltaic materials absorb a relatively narrow range of light energy [from one band gap].. Researchers from Lawrence Berkeley National Laboratory, the University of California, and MIT have engineered a single material that contains three bandgaps and is capable of capturing more than 50 percent of the sun's energy. The researchers made the material by forcing oxygen into a zinc-manganese-tellurium crystal. The oxygen split the crystal's band gap and formed a third one of its own. ..
It will take to three years to assess the technical feasibility of the multiband solar cell, according to the researchers. The work appeared in the December 12, 2003 issue of Physical Review Letters". See also here. 9:13:15 AM
