The Laquai group studies photophysical processes
such as exciton diffusion, exciton dissociation, charge carrier generation,
transport, and recombination in different photoactive materials and devices
including all-polymer and small molecule organic bulk heterojunction,
organic-inorganic hybrid, and perovskite solar cells by a combination of steady-state
and (ultrafast) transient all-optical and electro-optical techniques covering a
wide dynamic and spectral (frequency) range.
