Upright Orientation of Asymmetric Conjugated SAM Enables High‐Performance Perovskite Solar Cells
Self‐assembled monolayers (SAMs) are promising hole‐transporting interlayers for inverted perovskite solar cells (PSCs) owing to their ultrathin thickness and tunable work function. However, conventional SAMs such as Me‐4PACz tend to adopt lying‐down or tilted conformations on substrates, leading to disordered dipole o...
