Abstract Perovskite-organic tandem solar cells (P-O-TSCs) hold substantial potential to surpass the theoretical efficiency limits of single-junction cells. However, their performance is hampered by non-ideal interconnection layers (ICLs). Especially in n-i-p configurations, incorporation metal nanoparticles negatively introduces serious parasitic absorption, which alleviates photon utilization organic rear cell and decisively constrains maximum photocurrent matching with front cell. Here, we demonstrate an efficient strategy mitigate optical losses Au-embedded ICLs tailoring shape size distribution Au via manipulating underlying surface property. Achieving fewer, smaller, more uniformly spherical significantly minimizes localized plasmon resonance while maintaining electron-hole recombination within ICLs. Consequently, optimized P-O-TSCs combining CsPbI 2 Br various benefit from a current gain >1.5 mA/cm cells, achieving champion 25.34%. Meanwhile, contribute improved long-term device stability.

Abstract Perovskite/organic tandem solar cells (POTSCs) have garnered significant attention due to their potential for achieving high photovoltaic (PV) performance. However, the reported power conversion efficiencies (PCEs) and fill factors (FFs) are still subpar challenges associated with charge extraction in organic bulk‐heterojunction (BHJ) energy losses interconnecting layers (ICLs). Here, a quaternary BHJ blend is developed enhance subcell, contributing an increased FF of ≥78% under 1 sun illumination even more lower intensities. Meanwhile, ICLs reduced via incorporation self‐assembly monolayer (SAM), (4‐(3,6‐Dimethyl‐9H‐carbazol‐9‐yl)butyl)phosphonic acid (Me‐4PACz), form MoO x /SAM interface thorough control thickness suppress parasitic absorption. The resultant POTSCs achieve remarkable PCE 25.56% (certified: 24.65%), record 83.62%, which among highest PCEs all types perovskite‐based (TSCs) till now.
