Frank Dimroth (head of department III-V Epitaxy and Solar cells at Fraunhofer ISE) received his Diploma in physics from the University of Zurich, Switzerland, in 1996 and his Ph.D. in physics from the University of Constance, Germany, in 2000. He performed his Ph.D. thesis on ‚ÄúMetal organic vapour phase epitaxy for the fabrication of high-efficiency solar cells from III-V semiconductors‚ÄĚ at the Fraunhofer Institute for Solar Energy Systems (ISE). After a Postdoc at the University of Utah in Salt Lake City, he returned to Fraunhofer ISE as a senior scientist in 2001. Since 2007 he was named manager and later head of department ‚ÄúIII-V Epitaxy and Solar Cells‚ÄĚ with currently 60 employees. His main interests are high efficiency multi-junction solar cell architectures for next-generation photovoltaic devices. Within the last 15 years he performed applied research in the fields of space- and terrestrial concentrator photovoltaics for electricity and hydrogen production and published more than 150 scientific papers. Frank Dimroth was co-founder of Concentrix Solar in 2005, today part of Soitec. The company produces high-concentration photovoltaic systems previously developed in the group at Fraunhofer ISE. In 2009, his research group demonstrated for the first time a triple-junction solar cell with 41.1 % efficiency under concentration. Today, four-junction devices with up to 46.0 % efficiency have been achieved. Frank Dimroth and his team received the Fraunhofer price 2010, the prestigious French Louis D science award 2010 and the French-German Economy price 2011.
