Herein, an emerging acceptor L8-BO as the third component was combined with B1:BO-4Cl system for constructing efficient ternary all-small-molecule organic solar cells (ASM-OSCs). Theoretical, morphological, and crystallographic studies reveal that BO-4Cl possess good compatibility, resulting in alloy-like state formation of two acceptors blends. The synergistic effect is conducive to forming favorable phase separation molecular stacking promoting charge splitting extraction, which contributes simultaneously boosting short-circuit current density fill factor. Furthermore, higher lowest unoccupied orbital energy level assist ASM-OSCs achieving lower voltage loss respect binary devices. optimal 20 wt % deliver a top-level efficiency 17.10%. This work demonstrates not only morphology but also small matrix can be well-manipulated by employing strategy.
