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.
Philippe GilletPhilippe GILLET est entré à lEcole normale supérieure de la rue dUlm (Paris) pour y mener des études en sciences de la Terre. En 1983, il obtient un PhD en géophysique à luniversité de Paris VII et rejoint luniversité de Rennes I comme assistant. En 1988, titulaire dun doctorat dEtat, il devient professeur dans cette même université et la quitte en 1992 pour rejoindre Ecole normale supérieure de Lyon.
La formation des chaînes de montagnes, et des Alpes en particuliers, est lobjet de la première partie de sa carrière scientifique. En parallèle, il développe des techniques expérimentales (cellules à enclumes de diamants)qui permettent de simuler en laboratoire les conditions de pression et de température qui règnent au sein des planètes. Lobjectif de ces expériences est de comprendre de quels matériaux sont constituées les profondeurs inatteignables des planètes du système solaire.
En 1997, il commence à travailler sur la matière extraterrestre. Il participe à la description de météorites venant de Mars, de la Lune ou de planètes aujourdhui disparues et explique comment celles-ci ont été expulsées de leur planète dorigine par des chocs titanesques avant darriver sur Terre. Il a aussi participé au programme STARDUST de la NASA et contribué à lidentification de grains de comète ramenés sur Terre après avoir été capturés au voisinage de la comète Wild-II. Ces grains représentent les premiers minéraux de notre système solaire, formés il y a plus de 4,5 milliards dannées. Il a aussi travaillé sur les sujets suivants :
interactions entre bacteries et minéraux;
amorphisation sous pression;
techniques expérimentales: cellule à enclumes de diamant, spectroscopie Raman,diffraction des RX sur source synchrotron, microscopie électronique.
Philippe Gillet a aussi une activité de management de la science et de lenseignement. Il a ainsi dirigé lInstitut National des Sciences de lUnivers du CNRS (France), présidé le synchrotron français SOLEIL, lAgence Nationale de la Recherche française(2007) et lEcole normale supérieure de Lyon. Avant de rejoindre lEPFL il a été le directeur de cabinet du Ministre français de la Recherche et de lEnseignement Supérieur.

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.
