Dr. Hoepfner is the Director of the Fraunhofer Center for Sustainable Energy Systems. He is responsible for all strategic, financial and contractual aspects of this applied contract research center.
Christians personal research interests are based on the question how new technologies can be used to advance both the energy efficiency of our economy as well as the share of renewable energy generation, under consideration of our regulatory framework, political system, and consumer attitudes. An example of this work is the Fraunhofer Plug and Play PV systems project, which he leads as Principal Investigator.
Before joining Fraunhofer CSE, Christian was Vice President of Product Marketing and Management at Luminus Devices, which grew from an MIT start-up company to a world leader for specialty LED products. There, he was responsible for the successful commercialization of Luminus' high power light emitting diodes into the consumer electronics industry, and for introducing energy-efficient lighting products into energy savings markets.
Prior to this, he worked at LNL Technologies, Bandwidth Semiconductor, and Spire in a wide range of roles and technology areas, including lasers, photo detectors, III-V semiconductor device design and processing, planar light guides, and chemical vapor deposition. Christian received his PhD from the Free University Berlin, Germany, for work in thin film photovoltaics.
