microscopy and photovoltaic characterizations are used to study the influence of polymer
purification on the thermal properties of composite films of poly-3-hexylthiophene,(P3HT)
and methanofullerene ([6, 6]-phenyl C61 butyric acid methyl ester)(PCBM). DSC analysis
evidence that the composites prepared with commercial polymer, used as received, or after
purification have quite different thermal characteristics. These features, together with the …
