Y5 is a high-performance non-fullerene acceptor (NFA) th at uses an electron-deficient molecular core to obtain a low bandgap NFA and high absorption coefficient. OPV devices made from Y5 can reach high performances in single-junction devices. Y5 is versatile and can be employed in both conventional and inverted OPV device architectures and has reported PCE from 10.5 to 14.1% when paired with five different donor polymers.', 'Y5 is a highly efficient low band-gap non-fullerene acceptor. OPV devices made from Y5 can reach high performances in single-junction devices.
