Abstract
In this presentation, we report a novel π-extended low bandgap polymer, PITVT, which is composed of isoindigo and thienylvinylene. The polymer exhibits a high power conversion efficiency of 7.09% for polymer solar cells (PSCs). The high performance is achieved by strong intermolecular π-π stacking from coplanarity of thienylvinylene in polmyer backbone, and the deep HOMO energy level of PITVT. This work clearly demonstrates that the incorporation of π-extended thienylvinylene moiety in conjugated polymer backbone improves the performance of PSCs.
