Perovskite/organic tandem solar cells (POTSCs) are gaining attention due to their easy fabrication, potential surpass the S-Q limit, and superior flexibility. However, low power conversion efficiencies (PCEs) of wide bandgap (Eg) perovskite (PVSCs) have hindered development. This work presents a novel effective mixed-cation passivation strategy (CE) passivate various types traps in wide-Eg perovskite. The complementary effect 4-trifluoro phenethylammonium (CF3 -PEA+ , denoted as CA+ ) ethylenediammonium (EDA2+ EA2+ reduces both electron/hole defect densities non-radiative recombination rate, resulting record open-circuit voltage (Voc PVSCs (1.35 V) high fill factor (FF) 83.29%. These improvements lead PCE 24.47% when applied fabricated POTSCs, highest date. Furthermore, unencapsulated POTSCs exhibit excellent photo thermal stability, retaining over 90% initial after maximum point (MPP) tracking or exposure 60 °C for 500 h. findings imply that synergic surface passivators is promising achieve high-efficiency stable corresponding POTSCs.
