DESCRIPTION:Professor Jacques-Edouard Moser\nDynamics of light-induced cha
 rge separation in emerging photovoltaic systems\n\nAbstract\n\nPhotoinduce
 d interfacial electron transfer and charge separation into free carriers a
 re key processes that govern the efficiency of third generation photovolta
 ic technologies based on donor-acceptor heterojunctions. Rather than relyi
 ng on an electric field to separate charges of opposite signs\, these tech
 nologies are based on a kinetic competition between electron transfer and 
 recombination processes. Therefore\, it is necessary to employ time-resolv
 ed nanosecond to femtosecond spectroscopic methods to enhance the fundamen
 tal understanding of implied mechanisms and provide vital information that
  can aide in furthering material and device design. A combination of ultra
 fast optical and terahertz techniques was applied to scrutinize the dynami
 cs of photoinduced charge generation\, separation\, and transport in a var
 iety of dye-sensitized\, organic\, and hybrid lead halide perovskite solar
  cells\, as well as in strongly confined two-dimensional layers and nanopl
 atelets. Results obtained over the years evidence the convergence of the v
 arious emerging photovoltaic technologies and suggest a common picture for
  free carrier generation and separation in all types of donor-acceptor het
 erojunction systems.\n\nBiosketch\nJacques-Edouard Moser graduated as a ch
 emical engineer and obtained a doctorate (PhD) in physical chemistry (Mich
 ael Grätzel\, thesis advisor) from the École polytechnique fédérale de
  Lausanne (EPFL) in 1982 and 1986\, respectively.\nHe joined the Eastman 
 Kodak Corporate Research Laboratories at Rochester\, New York (USA) in 198
 6 as a postdoctoral fellow and was later associated with the NSF Center fo
 r Photoinduced Charge Transfer at the University of Rochester. Back in Swi
 tzerland\, he was appointed lecturer in physical chemistry at EPFL in 1992
  and was awarded the habilitation and the venia legendi in 1998. He was na
 med titular professor in 2005.\nSince 2005\, he has led the Group for Phot
 ochemical Dynamics at EPFL's Institute of Chemical Sciences and Engineerin
 g\, where his research has primarily focused on the ultrafast dynamics of 
 photogenerated charge carriers at donor-acceptor interfaces.\nJacques-E. M
 oser presided the Swiss Society of Photochemistry and Photophysics (SGPP).
  He was a member of the central board of the Swiss Chemical Society\, a me
 mber of the standing committee of the European Photochemistry Association 
 and a member of the executive committee of the Division for Fundamental Re
 search of the Swiss Chemical Society. He was director of the Section of Ch
 emistry and Chemical Engineering at EPFL and member of the direction of th
 e School of Basic Sciences from 2007 to 2015.\n\n\nAgenda\n17.15  - 18.15
