Abstract Carrier recombination loss within the emerging antimony selenosulfide (Sb 2 (S,Se) 3 ) photovoltaic devices is a critical factor limiting performance. Herein, reaction kinetics regulation strategy reported to simultaneously passivate deep‐level intrinsic defect and inhibit oxide impurities in Sb absorber with help of sodium borohydride (SB). The SB, on one hand due alkaline feature, can significantly promote decomposition selenourea Se formation, eliminating S1 defects reducing V S defects, other hand, owing property, restore SbO + ions 3+ , thus inhibiting O formation improving heterogeneous nucleation preferable [hk1] orientation. These collective influences have remarkably suppressed carrier strengthened collection optimal band alignment. Consequently, high‐efficient an efficiency 10.62% (0.0684 cm are gained, which comparable latest‐recorded value 10.7% (0.0389 ). This work provides feasible method for suppressing Sb‐based chalcogenide materials supplies precious instruction preparing high‐performance optoelectronic devices.
