A tetrachlorinated molecular non-fullerene acceptor for high performance near-IR absorbing organic solar cells

Abstract

We detail the physical properties and organic photovoltaic (OPV) performances of a tetrachlorinated fused ring non-fullerene acceptor. Introduction of chlorine atoms red-shifts the optical absorption out to 850 nm leading to low energy photocurrent generation in solar cell devices using the donor polymer PBDB-T. Processing films with different volatile solvent additives affects the active layer morphology and open-circuit voltage (Voc). Best solar cells exhibit power conversion efficiencies over 9%.
