Applications

ITIC-2F shows a more red-shifted absorption than ITIC with an improved absorption coefficient, which can be ascribed to enhanced intramolecular charge transfer. For this reason, devices with ITIC-2F as acceptors can cover a broader absorption spectrum - which can potentially enhance the device PCEs.

ITIC-2F also has deeper HOMO/LUMO energy levels. This makes it a better match for most polymer semiconductor donors, and provides better stability for device fabrication and overall performance.

Efficiency of over 13% was achieved when ITIC-2F (IT-4F) was used as an acceptor with polymer PBDB-T-SF as the active-layer donor material with a inverted device structure: indium tin oxide (ITO)/ZnO/PBDB-T-SF:TI-4F (1:1)/MoO3/Al [1].

We also now have ITIC-DCl available as another NFA for highly efficient organic solar cells.
