摘要：

Using a triple component random copolymerization approach, the amount of triethylene glycol (TEG) side chain, which can be regarded as a stack-inducing agent, is introduced precisely into a given polymer backbone. TEG side chains result in a more favorable morphology in a polymer:fullerene blend. Based on the low-bandgap photovoltaic polymer PBDTT-DPP (PBD), this methodology can bring a 10% overall improvement in power conversion efficiency (PCE). © 2013 WILEY-VCH Verlag GmbH & Co.
