Our group is interested in designing hybrid inorganic semiconductor/organic moieties systems where energy and/or charge can be extracted from photoexcited semiconductor nanostructures and transferred to species that are bound to their surfaces. Such motifs are of particular relevance for the design of energy-harvesting and energy-storage systems which are presently severely limited by loss processes that are not well understood. We are designing approaches aimed at unraveling the structural complexity of nanocrystalline surfaces in order to understand how specific surface defects modulate the properties of nanocrystals, including the study of non-radiative recombination processes that lead to energy losses in nanocrystal-based devices.
