Highlights • Dipolar molecules result in reduced device reliability of organic photovoltaics • Dipolar molecules tend to reorganize and reorient during device operation • Dipolar reorganization leads to increased dielectric constant and reduced performance Summary Blending two non-fullerene acceptors (NFAs) to form bulk heterojunctions (BHJs) in ternary organic photovoltaics (OPVs) has been shown to lead to an end-capping exchange reaction that results in the generation of several new dipolar...
