The design of self‐assembled monolayer (SAM) hole‐transport materials is essential for achieving efficient and stable organic solar cells. A series of asymmetric SAMs featuring isomeric skeletons were developed. These SAMs effectively modulate the work function (WF) of ITO, reduce energy barriers, improve molecular packing, and enhance surface coverage. These materials were successfully employed to fabricate highly efficient, stable, and reproducible organic solar cells. More details are discussed in the article by Chen et al . on pages 2870—2880. image
