Probing and manipulating the motion of electrons in complex solid state, molecular or
biological nanostructures in real time is a fundamental challenge in contemporary physics. It
is expected that an increased understanding of the underlying microscopic processes may
result in quite a number of novel applications, e.g., in optical and quantum information
technology or in photovoltaics. The experimental methods allowing to visualize these
complex processes, in particular time-resolved light-, x-ray and electron microscopy, are
currently undergoing an extremely rapid development. In my talk, I will present recent
experimental progress achieved in Oldenburg in this direction. Specifically, I will discuss the
role of quantum coherence for ultrafast charge separation processes in organic solar cells
[1,2]. Using recently ultrafast two-dimensional electronic spectroscopy, I will provide strong
evidence for persistent vibronic quantum coherences in prototypical polymer and solar cell
materials at room temperature and will discuss their effect on the light-induced charge
separation in these systems...
