Abstract

The performance and stability of organic photovoltaic (OPV) devices based upon bulk heterojunction blends of donor and acceptor materials have been shown to be highly dependent on the morphology of the active layer. Block copolymers, which naturally self-assemble into periodic ordered nanostructures, can be utilized in diverse ways to control morphology on a length scale relevant for charge separation, recombination and transportation, which makes them promising candidates for high performance and thermally stable OPV devices. This minireview presents a brief statistical discussion of inter-study correlations and a summary of past interfacial research on block copolymer nanostructuring compatibilizers for OPVs. © 2013 Society of Chemical Industry
