Director, Fraunhofer ISE
Andreas W. Bett is director of the Fraunhofer
Institute for Solar Energy Systems in Freiburg, Germany. His group is
well-known and active in the development of multi-junction solar cells and
holds the absolute solar cell efficiency record of 46.1%. This record was
achieved with a 4-junction monolithic concentrator solar cell made of III-V
materials. Recently a monolithic two-terminal triple-junction solar cell with
an active Silicon as bottom cell achieved another record value of 31.2% under
standard one sun testing condition.
Major awards includes the 17th European Becquerel Prize for outstanding merits in photovoltaics, the Joseph von Fraunhofer Prize and the EARTO Prize in 2010, and in 2012 the prestigious German Environmental Prize of the DBU for the outstanding contribution to commercialise the CPV technology.
