Fraunhofer ISE Develops the World's Most Efficient Solar Cell with 47.6 Percent Efficiency

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE, using a new antireflection coating, have successfully increased the efficiency of the best four-junction solar cell to date from 46.1 to 47.6 percent at a concentration of 665 suns. This is a global milestone, as there is currently no solar cell with a higher efficiency worldwide. The results are presented today at the 2nd International tandemPV Workshop, taking place in Freiburg, Germany.
