Abstract
Abstract The inhomogeneity of hole‐selective self‐assembled molecular layers (SAMLs) often arises from the insufficient bonding between anchors and metal oxide, particularly on textured silicon surfaces when fabricating monolithic perovskite/silicon tandem solar cells (P/S‐TSCs) and the hydrophobic carbazole complicates the fabrication of high‐quality perovskite films. To address this, we developed a novel bidentate‐anchored superwetting aromatic SAM based on an upside‐down carbazole core as a hole‐selective layer (HSL), denoted as ((9H‐carbazole‐3,6‐diyl)bis(4,1‐phenylene))bis(phosphonic acid) (2PhPA‐CzH). The bisphosphonate‐anchored exhibited enhanced adsorption capabilities and efficient hole…
