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.

Henrik Moodysson RønnowHenrik Ronnow was born in Copenhagen in 1974. He was awarded his master's degree in physics in 1996. Having earned his doctorate in 2000, he left Denmark for training at the Laue-Langevin Institute in Grenoble. Between 2000 and 2002, he held a Marie Curie Fellowship hosted by the Atomic Energy Commission. In 2002 he was appointed as an invited researcher at the NEC Laboratories in Princeton, then at the University of Chicago's James Franck Institute. In 2003, he became a researcher at the Laboratory for Neutron Scattering (Swiss Federal Institute of Technology in Zurich) and at the Paul Scherrer Institute. In 2007 he was appointed Assistant Professor at Ecole Polytechnique federale de Lausanne (EPFL). In 2012 he was promoted to Associate Professor.

Alexander TagantsevALEXANDER K. TAGANTSEV received the B.S. degree from St. Petersburg State University, in 1974, and Ph.D. degree from Ioffe Physico-Technical Institute, St. Petersburg, Russia, in 1982 in solid state physics. Before 1993, he worked in Ioffe Physico-Technical Institute, (1991-1993, head of laboratory), and St. Petersburg State Technical University (1991-1993, professor). He joined the ceramics laboratory of EPFL in 1993 where he was leading ( up to 2016) the section for Modeling and theory of Electroceramics. He is also currently engaged as a principle research fellow at Ioffe institute (St. Petersburg, Russia). Tagantsev is a theoretician of a broad domain of expertise from ferroelectricity and phonon physics to electrodynamics of superconductors and quantum optics. He is the author of key results on the theory of microwave dielectrics loss, dielectric polarization in crystalline materials, and relaxor ferroelectricity. He is also known in the field of ferroelectric thin films for elucidating works on the polarization switching and degradation in these systems. He authored or co-authored more than 300 scientific articles and two monograph (on domains in ferroics and tunable film bulk acoustic wave resonators). In 2007, Prof. Tagantsev was entitled to the Honors for lifetime achievement in the field of integrated ferroelectrics by the International Symposium on Integrated Ferroelectrics.
Franz-Josef HaugI studied Physics between 1990 and 1996 at the Universities of Ulm (Germany) and Waikato (New Zealand). While specializing mostly on Theoretical Physics and Quantum Theory during my studies, I turned towards Experimental Physics for a graduate work on gas-phase epitaxy of silicon. After that, I pursued a PhD program at ETH Zürich (Switzerland), studying Cu(In,Ga)Se2 solar cells. As PostDoc, I went to EMPA (Switzerland) to work on plasma processes for hard coatings of TiN and to the Jülich Research Centre in Germany to study light scattering ZnO front contacts for solar cells. In 2005 I joined the Institute of Microengineering (IMT) at the University of Neuchatel to lead a research group on thin film silicon solar cells within the PV-Lab. In 2009 the IMT was integrated into EPFL. My main research interests are optics, charge transport in semiconductors and renewable energy in general. My current work is devoted to passivating contacts for crystalline silicon solar cells, using thin silicon films as contact layers. In 2015 I was appointed Maitre d'Enseignement et Recherche (Senior Lecturer and Scientist) and member of the Faculty of STI. From 2013 to 2015 I was member of the EFPL Teachers Council (CCE) and from 2016 and 2018 I was elected into the Council of the Engineering School (CF-STI). In 2020 I was elected to become a member of CF-STI. My main objective for the legislature is to represent the role of EPFL's intermediate staff and to raise the awareness for concerns of the satellite campuses.
Christophe Marcel Georges GallandJ'ai étudié à l'Ecole Polytechnique Paris (X2003) et obtenu mon doctorat en 2010 à l'ETH Zurich pour une thèse en optique quantique sur les nanotubes de carbone, dans le groupe de photonique quantique du Prof. Ataç Imamoglu. En tant que chercheur postdoctoral au Los Alamos National Lab (États-Unis), j'ai étudié la photophysique des boîtes quantiques individuelles dans les groupes de Victor Klimov et Han Htoon. J'étudiais les mécanismes responsables des fluctuations de fluorescence et comment les contrôler. J'ai ensuite rejoint l'Université du Delaware et le groupe de Michael Hochberg pour travailler dans le domaine émergent de l'optique quantique intégrée. Je menais des projets internationaux tels que la réalisation d'une source sur puce de photons corrélés intégrant des filtres optiques et des démultiplexeurs. De 2013 à 2016, je travaillais à l'EPFL dans le groupe du Prof. Kippenberg dans le domaine de l'optomécanique quantique avec une bourse Ambizione du Fonds national suisse pour la recherche scientifique (FNS). Mon travail s'est concentré sur la création d'états vibrationnels non classiques d'oscillateurs mésoscopiques et sur l'amplification des vibrations dans les molécules. Depuis mai 2017, je dirige le Laboratoire de Nano-Optique Quantique à l'EPFL en tant que professeur financé par le FNS au sein de l'Institut de Physique. Mon équipe étudie deux phénomènes principaux: (i) la dynamique vibrationnelle des molécules couplées à des cavités plasmoniques à l'échelle nanométrique, et (ii) les corrélations non classiques médiées par des quanta individuels de vibrations cristallines -- à température ambiante. Nous utilisons des outils spectroscopiques de pointe tels que les lasers femtosecondes et les compteurs de photons uniques pour obtenir de nouvelles informations sur la dynamique à l'échelle sub-nanométrique.
