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.

Application

Y6 is a non-fullerene acceptor (NFA) that uses an electron-deficient molecular core to obtain a low bandgap 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.

To achieve net-zero emissions by 2050, renewable power contributions must triple. Photovoltaic stations provide vital utility power, achieved primarily through third- and fourth-generation technology. Promising trends include recycling and revolutionary, ultra-lightweight, flexible, and printable solar cells.

Professor Chen (Nankai University, China) and his team explain the strategies behind their recent record-breaking organic solar cells, reaching a power conversion efficiency of 17.3%.
