Researchers have found that the band gap of semiconductor indium nitride is not 2 eV as previously thought, but a much lower 0.7 eV. Scientists from the Lawrence Berkeley National Laboratory, Cornell University, and Japan's Ritsumeikan University have discovered that a single system of alloys incorporating indium, gallium, and nitrogen can convert virtually the full spectrum of sunlight to electrical current. Such a discovery could eventually lead to the delivery of the most efficient and relatively inexpensive solar cells. For more information, go to www.lbl.gov/science-articles/archive.
