Characterization of P3HT:PCBM blends by SANS measurements
Blends of poly-3-hexyl-thiophene (P3HT) and 6,6-phenyl-C61 butyric acid methyl ester (PCBM) are the most promising candidates for active layers of plastic solar cells with high... -
Electron spin relaxation measurements in polymeric systems
This proposal looks to study the electron spin relaxation using high field ALC measurements in two polymers, which differ only by the non-metal (i.e S or Se) in the polymer... -
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... -
Composition depth profiling of novel spray-coated plastic solar cell materials
We propose to study a range of new lower energy gap organic photovoltaic (OPV) materials deposited by spray coating using neutron reflectivity. The new materials to be studied... -
Determining the nanostructure of PCBM in thin film photovoltaics
Organic photovoltaics (OPVs) are a low cost alternative to existing photovoltaic materials. The efficiency of OPVs is steadily increasing towards the point where their cost per...
