In 2002 Dr. Marc Köntges received his Ph.D. in physics from the University of Oldenburg. After leading the “thin film technology” group at the Institute for Solar Energy Research Hamelin (ISFH) he became head of the group “Module Technologies” at ISFH in 2005. His group is well known for its work on cell cracks, electroluminescence and UV fluorescence of PV modules. In 2017 his group received the Innovation Award 2017 at the occasion of the Otti PV Symposium and the PV Magazine Award for a novel UV fluorescence method that allows fast module characterization in the field. His group also developed the “On Laminate Laser Soldering” technique (Reis Robotics Award 2008) and demonstrated the fabrication of a 20.2% efficient world record PERC module in 2016. Currently his research focus is the development of module technologies for highly efficient bifacial PERC+ solar cells.
