Proposed talk: Evaluating current inhomogeneities in solar cells by lock-in thermography for understanding their current-voltage characteristics
As an associate professor at Halle University he lectures on the physics of solar cells. He is the author of a book on Lock-in Thermography and has published more than 200 contributions about his research in scientific journals and at international conferences.
