Abstract The integration of organic dyes in perovskite solar cells (PSCs) to utilize near‐infrared (NIR) photons remains a challenge. In this study, selenium‐incorporated ortho‐benzodipyrrole‐based NIR dye CB‐2Se was developed. CB‐2Se, featuring lower bandgap 1.35 eV, blended with PCBM form bulk‐heterojunction layer PSCs for electron extraction and transport. Compared Y6‐16 acceptor, the removal Tz unit suppresses self‐aggregation, improving its compatibility PCBM. A CB‐2Se:PCBM‐incorporated PSC achieved remarkable power conversion efficiency (PCE) 25.18% V OC 1.164 V, J SC 25.71 mA/cm 2 , Fill Factor 84.15%, outperforming that PCBM‐only reference device (24.35%) PCBM:Y6‐16‐based (24.49%). PCBM:CB‐2Se enhanced long‐term stability PSCs, retaining 88% initial after 1000 h under ambient air thermal conditions. photophysical interactions between have been comprehensively investigated by using femtosecond transient absorption spectroscopy. Ultrafast exciton separation into free charges occurs within 200 femtoseconds at interfaces CB‐2Se. For first time, transfer holes from back detected, providing valuable insights charge dynamics utilizing dyes.
