Comprehensive Summary Herein, a theory‐guided ternary construction case on boosting power conversion efficiency (PCE) for all‐polymer solar cell (all‐PSC) is reported, where guest acceptor's characteristics include high miscibility with host polymer acceptor, significantly larger optical bandgap, and improved luminescence. Consequently, only 10 wt% PFFO‐Th (third component) addition, the PCE of binary control promoted to 18.55% from 16.69%, 11.1% relative increase, demonstrating great effectiveness this strategy. Besides, realized at state‐of‐the‐art level all‐PSCs processed by ortho ‐xylene, widely acknowledged green non‐ halogenated solvent field. This study shares new thought designing high‐performance photovoltaic devices reduced energy losses favorable charge dynamics, which would nourish future development all‐PSCs, even other organic electronics.
