High Purity, High Performance Acceptor Molecule

Non-fullerene acceptor with broad absorption spectrum

Part of our range of non-fullerene acceptors, ITIC-2F (also known as IT-4F) shows a more red-shifted absorption than ITIC with an improved absorption coefficient. This 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 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 [1]), an efficiency of over 13% has been achieved using ITIC-2F (IT-4F) as an acceptor and the polymer PBDB-T-SF as the active-layer donor material.

ITIC-2F from Ossila was used in the high-impact paper (IF 18.81), Stretchable and Transparent Conductive PEDOT:PSS-Based Electrodes for Organic Photovoltaics and Strain Sensors Applications, E. Dauzon et al., Adv. Fun. Mater., 30 (28), 2001251 (2020); DOI: 10.1002/adfm.202001251.

Our range of non-fullerene acceptors for highly efficient organic solar cells also includes ITIC and ITIC family members ITIC-DCl, ITIC-M, ITIC-Th, and ITIC-DM.
