Abstract
A photoactive interface is formed between an electrochemical generated organic polymer film and CdSe quantum dots. The specifically designed and synthesized 3,4 ethylenedioxythiophene electroactive monomer, holding C60 buckminsterfullerene, allows the formation of thin films containing both, electron acceptor and hole transport moieties. The generation of photoinduced heterogeneous charge transfer in CdSe quantum dots-electropolymer system was characterized by time resolved and spectral dependent surface photovoltage. In films containing C60 moieties whose surface was modified with 5nm CdSe quantum dots, the illumination generated photovoltage values around twenty times larger than those obtained without nanoparticles decoration. The results show that this organic-inorganic hybrid interface is a potential structure for the development of optoelectronic devices.
