ITIC (CAS number 1664293-06-4) represents the start of a new generation of non-fullerene acceptors for organic photovoltaics (OPVs). 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 molecules also have strong and broad absorption characteristics, from the visible region of the electromagnetic spectrum to the near infrared, peaking at 700 nm. This gives it the potential to increase the total absorption of an OPV device and enable improved power conversion efficiencies (PCEs). ITIC has also proved to have excellent thermal stability, with devices showing no losses after being held at 100 °C for 250 hours.

These properties have resulted in ITIC becoming the first small molecule electron acceptor to outperform the most efficient fullerene acceptor, PC₇₀BM, in an OPV device when fabricated in a controlled environment, such as a glove box. When used in conjunction with PBDB-T (PCE12) in an inverted-architecture device, ITIC enabled a power conversion efficiency of over 11% to be reached. By comparison, when PC₇₀BM was used as the electron acceptor, a PCE of less than 8% was achieved.

MSDS Documentation

ITIC MSDS Sheet

The ITIC family of NFAs includes ITIC and several derivatives, some of which offer higher power conversion efficiencies than ITIC itself. We stock a selection of high-purity ITIC derivatives for use in organic and polymer solar cells. Substituents such as fluorine and chlorine, which are electronegative, affect the HOMO and LUMO energy levels of ITIC-based acceptor molecules. In contrast, methyl groups can improve solubility, enhancing processability.
