Effect of Molecular Order on the Performance of Naphthobisthiadiazole-Based Polymer Solar Cells

Abstract

The influence of fullerene derivatives (PC60BM and PC70BM) and processing additives on the molecular order of a naphthobisthiadiazole-based polymer (NT) in the blend films differ significantly. This is strongly associated with the bulk heterojunction (BHJ) solar cell performance and affects charge recombination rates and sweep-out dynamics.
