If you have a question about this talk, please contact Dr. Girish Lakhwani. At Bath, we have developed a model of organic devices that links morphology to device characteristics. The model, based on the dynamical Monte Carlo approach pioneered in surface physics, allows us to include interaction processes between different species on many different timescales. In this talk I will show how we have used this approach to model the influence of interlayers, layers added to improve efficiency and lifetime, on organic light emitting devices, OLE Ds. Our model distinguishes between triplet and singlet excitons and allows for the interactions of these species (triplet-triplet annihilation, triplet-singlet annihilation, triplet-polaron quenching). I will show our predictions for emission zone profiles in a polymer device and discuss how we can gain insight into what determines changes in OLED efficiency with current and how in the longer term this approach can be used to address degradation.
