Hamburg Photon Science Colloquium | Coherent exciton-phonon dynamics in organic photovoltaics

by Irene Burghardt (Institute of Physical and Theoretical Chemistry, Goethe University Frankfurt, Germany)

Friday, November 9, 2018 from to (Europe/Berlin)
at DESY, Hamburg ( CFEL SR I-III (Bldg. 99) )
Description
The elementary processes of organic optoelectronics exhibit an intricate interplay of electronic delocalization, trapping phenomena, and coherent exciton-phonon and carrier-phonon dynamics in the subpicosecond domain. Against this background, the present talk highlights complementary results from time-resolved spectroscopy and high-dimensional quantum dynamics that elucidate the mechanism of conformationally driven exciton dynamics and exciton break-up at donor-acceptor interfaces.
