Abstract

Using flash photolysis, transient microwave conductivity we report some preliminary results on two polythiophene derivatives and compare the results with the ubiquitous poly(3-hexylthiophene). The data provide an insight into the efficiency of exciton dissociation into free charge carriers; a result that is of importance to bulk heterojunction, photovoltaic solar cells that are a construct of a blend of polymers of this type with the soluble fullerene, [6,6]-phenyl-C61-butyric acid methyl ester, (PCBM).
