ITIC-DCl, one of the out-performing ITIC family members, is always used as an acceptor material to replace fullerene in non-fullerene organic solar cells (NFA-OSCs) or non-fullerene polymer solar cells (NFA-PSCs). When compared with IT-4F (ITIC-2F), ITIC-DM exhibits lower HOMO/LUMO energy levels due to the partial larger dipole moment of the chloro-containing molecules.

Together with IT-2Cl as an acceptor material, ITIC-DCl achieved a power conversion efficiency (PCE) over 14% when PBDB-T-F was used as a donor polymer material. 

Devices architecture: ITO/PEDOT:PSS (35 nm)/PBDB-T-2F:IT-2Cl(20%):IT-4Cl(80%) (95-100 nm)/PFN-Br/Al (100 nm).
