Surfactant Induces Uniform and Stable Self‐Assembled Monolayers for High‐Performance Wide‐Bandgap Perovskite Solar Cells
Self‐assembled monolayers (SAMs) have been extensively studied in perovskite solar cells (PSCs). Nevertheless, the aggregation tendency of SAM molecules results in non‐uniform deposition and inadequate substrate coverage, thereby severely impeding device performance. Herein, we introduce a multifunctional additive, n...
