Effect of ester side chains on photovoltaic performance in thiophene-thiazolothiazole copolymers

Thiazolothiazole-based π-conjugated polymers are promising semiconducting materials in organic photovoltaics (OPV). A series of thiophene-thiazolothiazole based polymers having ester side chains, PTzBTE and PTzBTEE was synthesized. A new synthetic methodology for their common monomer having ester group, in which the total yield was significantly improved by a factor of ten compared to the previous methodology. This led to polymer samples with high molecular weights. OPV cells using PTzBTE, in combination with [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM), demonstrated high efficiencies of as high as 8.9% despite its limited absorption range. This value is significantly higher than that for PTzBT having only alkyl groups as the side chain and that obtained for a low-molecular weight PTzBTEE sample reported previously. Meanwhile, although PTzBTEE had a well-ordered structure like PTzBTE, it showed lower OPV performances. Investigations of electronic properties and structural order and morphology in thin films were performed. The OPV cells fabricated with a nonhalogenated solvent showed efficiencies comparable to the cells fabricated by a conventional halogenated solvent.
