In p–i–n (inverted) PSCs, fullerene its derivatives are widely employed as electron‐transport layers (ETLs). Among them, compatible with low‐temperature vacuum‐based cell processes. single layer tends form nonuniform due aggregation propensity. Furthermore, it struggles withstand damage that occurs during formation transparent conductive configurations. To overcome limitation fullerene, employing bilayer ETL emerged promising strategy.

Self-assembled monolayers (SAMs) have gained significant attention as an interfacial engineering strategy for perovskite solar cells (PSCs) due to their efficient charge transport ability and work function tunability. While solution-based methods such dip-coating spin-coating are widely used SAM deposition, challenges non-uniform coverage, solvent contamination, limited control over molecular orientation hinder scalability reproducibility. In contrast, vacuum deposition techniques, including thermal evaporation, overcome these limitations by enabling the formation of highly uniform materials with precise thickness arrangement. Importantly, chemical interactions between layers, coordination bonding Pb2+ ions, play important role in passivating surface defects, modulating energy levels, promoting crystallization. These not only enhance wettability but also improve overall quality stability films. This review highlights advantages vacuum-deposited SAMs, strong layers improving properties critical scalable applications.
