Abstract

Non-fullerene polymer solar cells (PSCs) attract more attention due to the constantly refreshed power conversion efficiency (PCE) based on the versatile non-fullerene acceptors. In this work, PCEs of 10.51% and 11.02% were obtained for two kinds of non-fullerene PSC with IDT6CN-M or ITCPTC as the acceptor and PBDB-T as the donor. ITCPTC has a relatively narrow bandgap and a high absorption coefficient compared with IDT6CN-M, which explains well the relatively large short-circuit current density of 17.44 mA cm^-2 for the ITCPTC based binary PSCs. Meanwhile, the IDT6CN-M based binary PSCs exhibit a relatively high fill factor (FF) of 75.3% and an open-circuit voltage of 0.915 V. A PCE of 11.92% and a FF of 76.5% were achieved for the ternary PSCs with 60 wt% ITCPTC content in the acceptors, which should be attributed to the enhanced photon harvesting and their good compatibility for a synergistic improvement of exciton utilization and charge transport in the ternary active layers. The FF of 76.5% is among the top values of ternary non-fullerene PSCs.
