ITIC-4F, high performance acceptor molecule
Non-fullerene acceptor with broad absorption spectrum, 99% purity
Part of our range of non-fullerene acceptors (NFAs), ITIC-4F (also known as ITIC-2F or IT-4F) is a derivative of ITIC. Compared to ITIC, ITIC-4F has a better absorption coefficient and a more red-shifted absorption. This can be ascribed to enhanced intramolecular charge transfer. Devices which use ITIC-4F as the electron acceptor can therefore cover a broader absorption spectrum, which may result in a better power conversion efficiency (PCE).
ITIC-4F also has deeper HOMO/LUMO energy levels than ITIC. This makes it a better match for most polymer semiconductor donors, and provides better stability for device fabrication and overall performance. Using an inverted device structure (indium tin oxide (ITO)/ZnO/PBDB-T-SF:TI-4F (1:1)/MoO3/Al ), an efficiency of over 13% has been achieved using ITIC-4F as the non-fullerene acceptor and the polymer PBDB-T-SF as the active-layer donor material.
