ITIC (n-type acceptor)

Product Code M1101-100mg
Price £250.00 ex. VAT

ITIC represents the start of a new generation of electron-accepting small molecules for organic photovoltaic (OPV) applications. The energy levels of ITIC allow for good alignment with low band-gap polymers, resulting in enhanced charge separation efficiency and reduced energy loss. ITIC also has strong and broad absorption characteristics, from visible to near infrared and peaking at 700 nm, giving it the potential to increase the total absorption of an OPV device.

ITIC from Ossila was used in the high-impact paper (IF 29.37), Triplet-Charge Annihilation in a Small Molecule Donor: Acceptor Blend as a Major Loss Mechanism in Organic Photovoltaics, J. Marin-Beloqui et al., Adv. Energy Mater., 2100539 (2021); DOI: 10.1002/aenm.202100539.

These properties have enabled ITIC to be the first small molecule to outperform fullerenes as the electron acceptor in an OPV device. When used in conjunction with PBDB-T (PCE12), a power conversion efficiency (PCE) of over 11% was achieved, compared to less than 8% when PC70BM was used as the electron acceptor.

ITIC has also proved to have excellent thermal stability, with devices showing no losses after being held at 100 °C for 250 hours [1].
