High-efficiency concentrator solar cells and modules
Climate change and ever scarcer fossil resources will determine the energy mix of the future. Solar energy will play an integral role in this regard. Dr Andreas Bett and Dr Frank Dimroth of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg developed metamorphic triple-junction solar cell consisting of III-V compound semiconductors: gallium indium phosphide, gallium indium arsenide and germanium. This special structure makes it possible to optimise the use of almost the entire solar spectrum for energy production. Researchers have been able to transform more sunlight into power than ever before, at a record degree of efficiency of 41.1 percent. In recognition of their work, they are receiving the 2010 Joseph von Fraunhofer Prize...
