Abstract

An analog of 1-(3-methoxycarbonyl)propyl-1-phenyl-[6,6]-methanofullerene (PCBM) was designed with the aim of improving miscibility with polythiophene donors, especially poly(3-hexyl thiophene) (P3HT). In the title compound the phenyl group from PCBM is replaced by a thienyl group, it is named 1-(3-methoxycarbonyl)propyl-1-thienyl-[6,6]-methanofullerene (ThCBM). In this letter, experimental studies of the morphology, charge transport, and solar cell performance in blends of P3HT:ThCBM are reported. This may open a route for the design of more specific fullerene based acceptor materials, which may optimize the morphology of bulk heterojunction photovoltaic devices with respect to their transport.
