Prof. Ilegems received an honorary doctorate from the University of Toulouse (1998) and the Heinrich Welker Award from the Compound Semiconductor Symposium (2006) for his contributions to III-V semiconductor materials and device research.
The research activities of the Semiconductor Device Physics Laboratory centred on the physics and technology of semiconductor devices. The main subjects of interest included quantum photonics (semiconductor microcavities, light emitting diodes, lasers and detectors), wide bandgap semiconductor nitrides, physics of nano and low-dimensional structures, high electron mobility transistors, crystal growth and materials technology. The research programs were carried out in close collaboration with numerous academic and industrial groups in Switzerland and abroad, in particular within the framework of programs of the European Community.

Christophe BallifChristophe Ballif is director of the Phototovoltaics and Thin Film Electronics Laboratoryb) (PV-Lab at the institute of microengineering (IMT) in Neuchâtel (part of the EPFL since 2009). The lab focus is on the science and technology of high efficiency heterojunction crystalline cells,so-called passivating contacts for solar cells, multi-junction solar cells include novel generation Perovskite on innovative optical high speed detector and on various macroelectronics application. It also deals with energy management with a focus on integration of solar electricity into the energy system. The PV-Lab has strongly contributed to technology transfer and industrialization of novel devices and full technology with numerous companies. Christophe Ballif graduated as a physicist from the EPFL in 1994, where he also obtained in 1998 his Phd degree working on novel PV materials. He accomplished his postdoctoral research at NREL (Golden, US) on compound semiconductor solar cells (CIGS and CdTe). He worked then at the Fraunhofer ISE (Ge) on crystalline silicon photovoltaics (monocrystalline and multi-crystalline) until 2003 and then at the EMPA in Thun (CH) before becoming full professor at the University of Neuchâtel IMT in 2004, taking over the chair of Prof. A. Shah. Since 2013, C.Ballif is also the director of the new CSEM PV-Center, also located in Neuchâtel. The CSEM PV-Center is focussing more on industrialisation and technology transfer in the field of solar energy, including solar electricity management and storage.
