Abstract The power conversion efficiencies (PCEs) of single‐junction organic solar cells (OSCs) have surpassed 19%, owing to the emerging Y‐series nonfullerene acceptors (NFAs). Undoubtedly, and flexibility chemical design has been a strong driver for this rapid efficiency improvement in OSC field. Over course past 3 years, variety modifications made structure Y6 acceptor, large number NFAs reported further improve performance. Herein, we present our insights into rationale behind acceptor discuss principles toward high‐performance NFAs. It is clear that structural through choice heteroatom, soluble chains, π spacers, central cores, end groups alter material characteristics properties, contributing distinctive photovoltaic Subsequently, analyze various strategies Y‐series‐containing materials, including polymerized small‐molecule (PSMA), non‐fused‐ring (NFRA), all‐fused‐ring (AFRA). This review expected be value providing effective molecular future innovations.

Core engineering plays a vital role in the construction of efficient non-fullerene acceptors. Here, we synthesized molecule named QX, based on core quinoxaline, and by replacing H atoms with 2-ethylhexyl, 2-(ethylhexyl)thiophene, 2-(2-ethylhexyl)-3-fluorothiophene groups, obtained other three acceptors, QX-EH, QX-TH, QX-THF, respectively. Compared introduction substitution groups ameliorated molecular solubility, their lowest unoccupied orbital levels were elevated. Also, thiophene ring QX-TH QX-THF enhanced miscibility PM6 compared to QX-EH. Furthermore, fluorine atom greatly optimized blend morphology, leading charge transport, less bimolecular recombination, suitable nanophase aggregation devices. Eventually, PM6:QX-THF-based devices exhibited an impressive power conversion efficiency 17.45% fill factor 78.99%. This work reveals that modification quinoxaline is effective tuning morphology open-circuit voltage for high-efficiency organic photovoltaics.
