ITIC-M, non-fullerene acceptor for high-efficiency polymer solar cells

Low price, high purity (≥99%) ITIC-M, quantities from 50 mg to 1 g available

ITIC-M, or IT-M, is a non-fullerene, small-molecule acceptor that is used for high-efficiency polymer solar cells. ITIC acceptors like ITIC-M have the benefit of strong and broad absorption (from visible to near infrared) with good energy level alignment to low band-gap polymer semiconductors.

Being slightly more electron-rich than ITIC, ITIC-M has a higher energy level with an elevated LUMO level to increase Voc for OPV devices, thus improving the overall power conversion efficiency (PCE). Methyl groups on the phenyl rings also increase the solubility of the structure, and help ITIC-M to have greater miscibility with polymer donors.
