Flexible perovskite solar cells (f-PSCs) have emerged as potential candidates for specific mechanical applications owing to their high foldability, efficiency, and portability. However, the power conversion efficiency (PCE) of f-PSC remains limited by inferior contact between flexible buried substrate. Here, an asymmetric π-extended self-assembled monolayer (SAM) (4-(9H-dibenzo[a,c]carbazol-9-yl)butyl)phosphonic acid (A-4PADCB) is reported a substrate efficient inverted f-PSCs. Employing this design strategy, A-4PADCB exhibits significant orientation angle away from surface normal, homogenizing distribution potentials. This enhancement improves SAM/perovskite interface quality, controlling growth favorable films with low defect density slight tensile stress. Integration into small-area f-PSCs large-area modules aperture area 20.84 cm

Abstract Mixed‐halide perovskites are emerging as excellent photovoltaic candidates because of their tunable bandgaps for semitransparent and tandem perovskite solar cells. However, the notorious film quality originated from rapidly downward crystallization process susceptibly propagates enormous detrimental defects, which deteriorate performance accelerate halide segregation. To address this issue, herein, a multilayer alkalis‐intercalated‐vermiculite is employed pre‐buried interface modifier to regulate lattice property. The matchable structure between vermiculite by forming Pb─O bond not only releases interfacial strain during growth but also embedded alkalis ions can gradually diffuse into form favorable vertical gradient owing weak interlamellar van der Waals interaction, playing bis‐roles atomical lubricant ion‐reservoir eliminate defects. As result, stability significantly improved with suppressed phase segregation mixed‐halide perovskites, accompanying champion efficiency 11.42% carbon‐based CsPbIBr 2 device, 15.25% CsPbI Br device 23.17% p‐i‐n inverted (Cs 0.05 MA FA 0.9 )Pb(I 0.93 0.07 ) 3 cell. This work provides new strategy on buried engineering making high‐efficiency stable platforms.
