The development of high‐performance perovskite solar cells (PSCs) and perovskite‐based tandem (PTSCs) has attracted significant attention from researchers owing to their simple cost‐effective fabrication process. However, careful consideration is required regarding the selection charge‐transport layers, which play a key role in improving efficiency stability devices. 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. Therefore, this study, evaporation processes for ETLs inverted PSCs focused on, emphasizing importance architectures enhancing durability PTSCs. discussion highlights material options examines optimal thickness parameters achieve superior efficiency. By providing comprehensive understanding ETLs, review aims guide future advancements PTSCs technologies.
