Non fullerene acceptor Y6 – Sigma-Aldrich
RM1,928.00Brand:
Sigma-Aldrich
Synonyms
BTP-4F, Y6, PCE 157
CAS No
2304444-49-1
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.
Y6 is a non-fullerene acceptor-donor-acceptor (A-D-A) type small molecular acceptor (SMA) with flexible alkyl chains and a centrally fused ring. It has a ladder-type electron-deficient core, which can be blended with PM6 for organic photovoltaic applications.
Applications
Y6 is a non-fullerene acceptor (NFA) that uses an electron-deficient molecular core to obtain a low band gap with improved electron affinity. OPV devices made from Y6 can reach exceptionally high performances in single-junction devices, with a maximum PCE reported of 15.7% (14.9% certified by Enli Tech Laboratory) when paired with PM6. Y6 is versatile and can be employed in both conventional and inverted OPV device architectures and can maintain a high PCE with varying active layer thicknesses (13.6% in thick 300 nm layers).
Y6 is used as an electron acceptor material in organic solar cells. It has shown promising results in improving the power conversion efficiency of organic solar cells. Y6 and its derivatives are also used in material engineering studies to understand the relationships between molecular structure, morphology and device performance in organic photovoltaics.
