On November 11, 2016 at the Konzerthaus in Freiburg, the Fraunhofer Institute for Solar Energy Systems ISE honored Prof. Eicke R. Weber’s achievements at a scientific symposium on the global energy transformation. Having reached retirement age, Prof. Weber will step down from his position as Institute Director at the end of the year. Weber gave the German solar research a voice that is observed worldwide. With great enthusiasm he supported the energy transformation on both the scientific and political arenas. At the Institute, he organized the structure and business areas to optimally meet the demands of the energy transformation. From 2006 to 2016, he was able to double the number of employees to 1100 today. Over the same time period, the operating budget, based primarily on self-acquired projects, grew from ca. 25 million euros up to 73 million euros (2015).
