Thin Film Morphology in Polymer-Fullerene Bulk-Heterojunctions Materials
A promising class of materials for solar energy is conjugated polymer (CP)-fullerene mixtures. They offer the future potential for replacing current inorganic systems with... -
An off-specular neutron scattering study of the 'peristaltic mode' in the dew...
We plan to use the OFFSPEC SPIN-Echo reflectometer to study the mechanism of the 'peristaltic mode' in the spinodal dewetting of thin polymer films. In the peristaltic mode the... -
Lateral Phase Behavior in bulk heterojunction films containing low-molecular ...
Grazing incidence small angle neutron scattering (GISANS) will be used to investigate the lateral phase behavior in thin films of blends of electron-donor... -
Effects of Architecture on Polymer Diffusion
As part of a wider study we are studying the effects of polymer architecture between cyclic and linear polymers. From ATR-FTIR measurements we observe clear differences between... -
Determination of fullerene-polymer interactions
Fullerenes often produce very dramatic improvements to polymer properties, but their limited miscibility with polymers is often a severe restriction to the general utility. We... -

Phase behaviour in Polymer-Photovoltaic Thin Film Blends
In polymer-fullerene based photovoltaic systems the phase behaviour of the blends is poorly understood and remains a fundamental stumbling block to improvements in device... -
Solid state processing of conjugated polymer-fullerene blends
Blends of fullerenes with conjugated polymers (CP), such as PCBM-P3HT blends, are being extensively investigated for polymer photovoltaic applications. We have been studying the... -
