Title: Influence of bias voltage and temperature on charge transfer states in organic photovoltaic and electroluminescent integrated device

Based on the organic photovoltaic (PV) and electroluminescent (EL) integrated device with a structure of SubPc/C{sub 60} heterojunction, both PV and EL properties of charge transfer states (CTSs) were simultaneously investigated. By means of infrared and visible isolating method, the EL characteristics of CTSs and singlet-triplet excitons were separated, and their properties dependence on bias voltage and temperature was analyzed by introducing modified diode models. From the simulation on the emissive photons from CTSs, the temperature independent parameters of CTSs were extracted, which have close relationship with thermal activation energy and effective emissive state number of CTSs at the SubPc/C{sub 60} interface.
