The influence of electric fields on the time-resolved luminescence of hybrid organic-inorganic structures — •jȩdrzej szmytkowski^1,3, jonas conradt¹, peter marek², teodor silviu balaban^2,3, and heinz kalt^1,3 — ¹Universität Karlsruhe (TH), Institute of Applied Physics, Karlsruhe, Germany — ²Karlsruhe Institute of Technology (KIT), Forschungszentrum Karlsruhe, Institute of Nanotechnology, Karlsruhe, Germany — ³Center for Functional Nanostructures (CFN), Karlsruhe, Germany

The understanding of the process of electron transfer from an organic dye to inorganic material, like TiO₂ and ZnO, is crucial for the fabrication of efficient hybrid solar cells. Time resolved luminescence studies within applied external electric fields have been performed for several hybrid organic-inorganic structures. The decay associated spectra (DAS) have been used to analyze the dynamics of the luminescence decay. This method allows us to control the dissociation of excitons at the interface of organic-inorganic bilayers.
