Abstract Self-assembled monolayers (SAMs) represent an effective strategy for the development of perovskite solar cells (PSCs). High-performance PSCs are typically fabricated in an inert atmosphere because ambient moisture disrupts phosphonic-acid SAMs on transparent conductive oxides, leading to surface inhomogeneity and direct exposure of the transparent conductive oxide. However, this dependence on glovebox fabrication constrains scalability and cost-effective manufacturing.

1 Introduction Halide perovskites are widely utilized in both tandem and single-junction solar cells due to their bandgap tunability through compositional adjustments.[1] Among lead halide perovskites, formamidinium lead triiodide (FAPbI3), which has the lowest bandgap, is predominantly used in single-junction solar cells.[2] In contrast, tandem solar cells employ mixed-ion wide-bandgap perovskites (WBPs) with bandgaps ranging from 1.65 to 1.75 eV to ensure current matching with the bottom...
