摘要：

High-powered polymer: Fluorinated benzothiadiazole was incorporated into a polymer that was used in a high-performance solar cell. The model polymer 2 has decreased HOMO and LUMO energy levels and a similar band gap when compared with its nonfluorinated analogue 1. A bulk heterojunction device derived from 1 demonstrated a high power conversion efficiency of 7.2% (5.0% for 1). (Chemical Equation Presented). © 2011 Wiley-VCH Verlag GmbH & Co. KGaA.
