Aurelio BayAurelio Bay graduated in physics at the University of Lausanne (UNIL) in 1980 and got his PhD degree from the same institution in 1986 for a work on the determination of the axial form factor of the ? meson.
He then went to Lawrence Berkeley Laboratories (LBL), USA as a post doc for two years, where he worked on the TPC/2? Electromagnetic Calorimeter and the SSC/LHC detector. He then came back to Europe and was named Maître Assistant at University of Geneva till 1994, where he started working at the L3 experiment of LEP at CERN.
He was appointed Assistant Professor at the University of Lausanne in 1994 and Full Professor in 1998, continuing working at LEP, LEP2 and LHCb at CERN , and starting a collaboration at BELLE experiment at KEK, Tsukuba (Japan).
At the University of Lausanne he was Director of the Institute of High Energy Physics, Deputy Director of the Physics Department and Deputy of the Dean of the Faculty of Sciences.
In 2003, following the merge of UNIL physics department into the EPFL School of Basic Sciences, he was appointed Full Professor at Ecole Polytechnique Fédérale de Lausanne (EPFL), and Director of the EPFL Laboratory of High Energy Physics.
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. At the core of the CSEM PV-center activities lies several "pilot lines" for various kinds of solar cells manufacturing, with a focus coating technologies, wet chemistry processes for crystalline silicon, metalisation techniques for solar cells, and a platform for developing "ideal packaging solutions and polymers" for PV modules. In addition, joined facitilites between CSEM and EPFL of over 800 m2 are available for modules manufacturing, measuring and accelerated aging. CSEM PV-center has also full team dedicated to storage and energy systems and operates a joined center with BFH in Biel for research on electrochemical storage. He (co-) authored over 500 journal and technical papers, as well as several patents. He is an elected member of the SATW, member of the scientific council of the Swiss AEE, and member of the board of the EPFL Energy center. In 2016, he recieved the Becquerel prize for his contributions to the field of high efficiency photovoltaics.
