Abstract
The paper presents a procedure of estimating the efficiency of exciton splitting at ED/EA interface. The procedure consists in evaluation of splitting of excitons into electron-hole pairs on the basis of the external quantum efficiency spectra of planar cells and spectra of absorbance of active organic layers. The fitting parameters are the exciton splitting probabilities at ED/EA interface. The presented procedure was applied to two different photovoltaic systems: ITO/MoO3/DBP/PTCBI/BCP/Ag and ITO/MoO3/DBP/F16ZnPc/BCP/Ag with quite similar energy diagrams at the ED/EA interface. The analysis performed led us to the conclusion that only the DBP/PTCBI interface can be considered attractive for organic photovoltaics and organic photodetection, while the DBP/F16ZnPc interface does not show any favourable properties for such applications.
