| Application: | F-M is a non-fullerene acceptor that absorbs visible light, when used in a front cell paired with NIR absorbing rear cell, the resulted tandem organic solar cell gave a record energy conversion efficiency of 17.3%. Tandem Cell Device performance: ITO/ZnO/PFN-Br/PBDB-T:F-M Voc=1.642 V Jsc=14.35 mA/cm2 FF=73.7% PCE=17.3% |
| 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. |
