Submission + - Full spectrum solar cells (lbl.gov) 1

Diego Manuel writes: "BERKELEY, CA — Researchers in the Materials Sciences Division (MSD) of Lawrence Berkeley National Laboratory, working with crystal-growing teams at Cornell University and Japan's Ritsumeikan University, have learned that the band gap of the semiconductor indium nitride is not 2 electron volts (2 eV) as previously thought, but instead is a much lower 0.7 eV. The serendipitous discovery means that a single system of alloys incorporating indium, gallium, and nitrogen can convert virtually the full spectrum of sunlight — from the near infrared to the far ultraviolet — to electrical current"

  • Isn't indium rather rare? $300+ per lb? Wouldn't that make its use in solar cells prohibitively expensive? (Except maybe in space applications where reducing weight is paramount...)
