Non-fused core with non-covalent interactions refines the film-forming kinetics of star-shaped oligomer acceptors for achieving long-term stable solar cells with 19.27% efficiency.
In this review, we carefully review important strategies to improve the stability of OSCs in the past three years from the perspectives of material design and device engineering.
This review summarizes the recent progress, challenges, and future perspective towards stable non-fullerene organic solar cells (NF-OSCs) with detailed discussion of various aspects and effective strategies to improve the stability of NF-OSCs.
Two oligomer acceptors with a specific A–DA′D–A structure and different π-bridge lengths were constructed for organic solar cells, and the PM6:CH-TRZ binary solar cell achieves an impressive efficiency of 17.07% along with excellent device stability.
This perspective summarizes the advances in quinoxaline-based acceptors for organic solar cells and suggests several potential directions for further research.
