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 V_oc 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.
