Application

Y6 (BTP-4F) is a popular non-fullerene acceptor (NFA) molecule for use in Organic Photovoltaic (OPV) given its contribution to device power conversion efficiencies (PCEs). Also known BTP-4F, Y6 is a highly conjugated electron deficient organic semiconductor with an A-DAD-A structure. The absorption spectrum of Y6 molecule has a maximum at around 810 nm and extends to 1100 nm. This means that Y6 and its polymer blends have the potential to absorb light across the entire visible and near infra-red spectrum.
