General description

Non-fullerene acceptors (NFAs) are currently a major focus of research in the development of bulk-heterojunction organic solar cells (OSCs). In contrast to the widely used fullerene acceptors (FAs), the optical properties and electronic energy levels of NFAs can be designed and readily tuned. NFA-based OSCs can also achieve greater thermal stability and photochemical stability, as well as longer device lifetimes, than their FA-based counterparts. Recent developments have led to a rapid increase in power conversion efficiencies for NFA OSCs, with values now exceeding 15% in a single junction cell, and >17% for a tandem cell, demonstrating the viability of using NFAs to replace FAs in next-generation high-performance OSCs.

Application

Y5 is a high-performance non-fullerene acceptor (NFA) that 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.
