摘要	All-perovskite tandem solar cells (PTSCs) demonstrate higher power conversion efficiency (PCE) and lower levelized cost of electricity than single-junction perovskite solar cells (PSCs). However, narrow bandgap (NBG) sub-cells with a Sn-Pb alloy cause severe p-type self-doping by surface oxidized Sn4+ to generate substantial energy loss and device degradation. Here, we developed a one-step self-assembly strategy to construct a p/p- homojunction of Sn-Pb perovskite using the antioxidant 4-trifluoromethylphenylhydrazine hydrochloride (TFPHCl) and prepared highly efficient and stable NBG PSCs. Self-floating TFPH cations allowed effective defect passivation and inhibition of Sn2+-Sn4+ oxidation, leading to a weak p-type surface (p-). Hence, the as-formed p/p- homojunction in turn accelerated the charge separation and reduced the non-radiative recombination. TFPHCl-modified NBG PSCs reached a stabilized PCE of 23.09% with an open-circuit voltage (Voc) of 0.88 V and excellent operational stability over 780 hours. Coupled with wide bandgap (WBG) subcells, TFPHCl-modified PTSCs ultimately attained an optimal PCE of 27.42% with long-term operational stability over 450 hours. Self-assembly construction of a homojunction with antioxidant encapsulation for efficient and stable narrow bandgap perovskite solar cells and all-perovskite tandem solar cells.
