Abstract Simultaneously mitigating both photovoltage and photocurrent losses is crucial for organic solar cells (OSCs) to approach the Shockley–Queisser limit of ideal efficiency. Incorporating a narrower bandgap nonfullerene acceptor (NFA) as guest component into host donor:NFA system broadens absorption spectrum. However, this can also increase nonradiative decay rate according energy‐gap law. In work, ternary OSCs are constructed by combining narrow AQx‐2F (as NFA) with lower eC9 NFA), significantly enhancing generation without compromising photovoltage. The addition acts crystallization inducer, extending period increasing ordered packing distance. This leads suppressed trap states, elevated dielectric constant, prolonged exciton lifetime, balanced hole/electron transport, reduced recombination loss. Consequently, optimized D18:AQx‐2F:eC9 achieve champion power conversion efficiency (PCE) 20.6% high open‐circuit voltage 0.937 V, short‐circuit current density 27.2 mA cm −2 fill factor 80.8%, validated an independently certified PCE 20.0%, establishing new benchmark bulk heterojunction OSCs. work demonstrates effective method simultaneously mitigate losses, paving way high‐performance
