Hot Electrons Could Double Solar Power - Researchers at Boston College have provided new experimental evidence that solar cell output can be double vi the use of "hot electrons." Ordinary solar cells can, in theory, convert at most about 35 percent of the energy in sunlight into electricity, wasting the rest as heat. Making use of hot electrons could result in efficiencies as high as 67 percent. (MIT Technology Review Dec. 18, 2009)
