Abstract Self‐assembled monolayers (SAMs) have recently emerged as promising candidates for interfacial materials in organic photovoltaics (OPVs). However, the quality and integrity of SAM growth are significantly influenced by surface morphology indium tin oxide (ITO) substrates, which can compromise performance reproducibility OPVs. To achieve controlled high‐quality SAMs assembly, this study presents an effective strategy to eliminate sensitivity polycrystalline ITO depositing amorphous molybdenum trioxide (MoO 3 ) thin layer on top. The application MoO homogenize roughness circumvent issues related preferential grain orientation distinct boundaries associated with ITO. This results a more uniform denser coverage compared direct bare Consequently, resulting OPVs based PM6/BTP‐eC9 system exhibit outstanding power conversion efficiency 19.9% (certified at 19.3%), primarily due reduced defects optimized active morphology. More importantly, introduction between enhances long‐term stability devices those solely SAMs. progress highlights importance refining microstructure facilitate favorable formation subsequently construct high‐performance

Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has been widely used as a hole transporting layer (HTL) in two-dimensional (2D) Ruddlesden-Popper perovskite (RPP)-based solar cells (2D-PSCs) due to its simple preparation process and low cost. However, the devices based on PEDOT:PSS exhibit efficiency poor stability number of buried interfacial defects, energy level mismatching, corrosivity HTL. In this study, guanidinium iodide (GAI)-modified HTL was adopted tune crystallization 2D RPPs, leading formation films with preferential crystal orientation, improved crystallinity, suppressed defect density. The addition GAI not only enhances conductivity intrinsic layers but also improves their matching those films. Upon doping into PEDOT:PSS, power conversion 2D-PSCs increased from 13.11% 16.04% maintained 80% initial value under 65% relative humidity condition for 60 days. This work demonstrates novel synergetic modification strategy gives new insight underlying mechanism, which should lead further improvements performance other optoelectronic RPPs.
