On June 26, 2025, Prof. Dr.-Ing. Bruno Burger was farewell as a lecturer at ETI. Since 2000, he had been giving lectures in the field of solar cells and since 2004 the lecture "Power Electronics for Photovoltaics and Wind Energy." Bruno Burger began his studies at the then University of Karlsruhe in 1985, completed his diploma in 1991, and successfully finished his doctorate at ETI in 1997. He was then significantly involved in the development of the Fraunhofer ISE in Freiburg. With the best wishes for the future, Prof. Hiller and Prof. Doppelbauer, along with the students and staff of ETI, bid farewell to Bruno Burger. They presented him with a model of a motor made in the ETI workshop as a keepsake of the wonderful time at ETI. Mr. Burger emphasizes at his farewell that it has always been a great joy for him to work with the students and to inspire them for renewable energies.

We wish him only the best for his well-deserved retirement and will continue to eagerly follow the Energy-Charts.
