Solution‐State Supramolecular Engineering of Self‐Assembled Monolayers for High‐Performance Perovskite/Silicon Tandem Solar Cells
Carbazole‐based self‐assembled monolayers (SAMs), exemplified by [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz), are widely used as hole‐selective contacts in efficient perovskite/silicon tandem solar cells (TSCs). However, aggregation‐driven intermolecular organization in solution adversely aff...
