Abstract Perovskite solar cells (PSCs) are promising for high‐efficiency tandem applications, but their long‐term stability, particularly due to ion migration, remains a challenge. Despite progress in stabilizing PSCs, they still fall short compared mature technologies like silicon. This study explores how different piperazinium salt treatments using iodide, chloride, tosylate, and bistriflimide anions affect the energetics, carrier dynamics, stability of 1.68 eV bandgap PSCs. Chloride‐based achieved highest power conversion efficiency (21.5%) open‐circuit voltage (1.28 V), correlating with stronger band bending n‐type character at surface. At same time, showed reduced increased ionic losses. Tosylate‐treated devices offered best balance, retaining 96.4% after 1000 h (ISOS‐LC‐1I). These findings suggest that targeted surface can enhance both

Abstract We report a highly crystalline self‐assembled multilayer (SAMUL) that is fundamentally different from the conventional monolayer or disordered bilayer used for hole‐extraction in inverted perovskite solar cells (PSCs). The SAMUL can be easily formed on ITO substrate to establish better surface coverage enhance performance and stability of PSCs. A detailed structure‐property‐performance relationship molecules established through systematic study their crystallinity, molecular packing, hole‐transporting properties. These SAMULs are rationally optimized by varying structures deposition methods thermal evaporation spin‐coating fabricating CbzNaphPPA‐based was chosen PSCs due it exhibiting highest crystallinity hole mobility which derived ordered H‐aggregation. This resulted remarkably high fill factor 86.45 %, enables very impressive power conversion efficiency (PCE) 26.07 % achieved along with excellent device (94 its initial PCE retained after continuous operation 1200 h under 1‐sun irradiation at maximum point 65 °C).
