Equilibration and reversibility in polymer/fullerene nanocomposites; continuation proposal
Organic photovoltaics (OPVs) are candidates for the large-scale capture of solar radiation, due to the potential to process these materials in large areas at low cost. However, considerable challenges exist in terms of lifetime and robustness of performance. This proposal forms part of a wider effort in which our motivation is to complement device optimisation strategies with in-depth studies of model systems, aimed at increasing the fundamental understanding of the materials science within polymer nanocomposite thin-films. This continuation proposal seeks to confirm preliminary results pointing to non-monotonic equilibrium behaviour as a function of temperature. Measurements will be performed on polystyrene (PS)/bis-adduct phenyl-C60-butyric acid methyl ester (bis-PCBM) bilayers. We will also repeat and extend measurements on the approach to equilibrium from different starting positions in phase space. Accessing the buried interface between the separated phases at elevated temperature via in-situ reflectivity measurements is the key to these experiments, allowing the probing of composition profiles at and on the way to equilibrium, and also enabling the testing of reversibility.
