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.

Abstract The antisolvent‐assisted spin‐coating still lags behind the thermal evaporation method in fabricating perovskite films atop industrially textured silicon wafers making monolithic perovskite/silicon solar cells (P/S‐TSCs). inhomogeneity of hole‐selective self‐assembled monolayers (SAMs) often arises from insufficient bonding between hygroscopic phosphonic acid anchors and metal oxide. To address this, a mixed‐SAM strategy (Mx‐SAM) is proposed to enhance adsorption energy SAMs on ITO surface, facilitate formation dense humidity‐resistant layer (HSL) substrates, improve hole transport capabilities. With aid Mx‐SAM strategy, optimized wide‐bandgap PSCs achieved an impressive power conversion efficiency (PCE) 22.63% with exceptionally high fill factor ( FF ) 86.67% using 1.68 eV perovskite. Moreover, they exhibited enhanced stability under damp‐heat conditions (ISOS‐D‐3, 85% RH, 85 °C) T 90 900 h for encapsulated PSCs, representing one best performances PSCs. When further extending P/S‐TSCs industry, remarkable 28.07% reached while upholding outstanding reproducibility. This holds significant promise feasibility industrially‐compatible P/S‐TSCs.
