ITIC-4Cl for non-fullerene organic or polymer solar cells

Low price, high purity (≥99%), available in quantities from 50 mg to 1 g


ITIC-4Cl, a high performing ITIC derivative also known as ITIC-DCl or IT-4Cl, is a non-fullerene acceptor material which can be used to replace fullerene acceptors in non-fullerene organic solar cells (NFA-OSCs) or non-fullerene polymer solar cells (NFA-PSCs). Compared to ITIC-4F, it has lower HOMO/LUMO energy levels. This is due to the partial larger dipole moment of the chloro-containing molecules.

Together with IT-2Cl as an acceptor material, a power conversion efficiency (PCE) of over 14% has been achieved using ITIC-4Cl, with PBDB-T-F as a donor polymer material.
