Self-assembled monolayer (SAM)-based inverted perovskite solar cells (PSCs) have exhibited excellent performance in efficiency, while the stability and reproducibility of PSCs still need to be improved. In this work, we present a multifunctional hole transport approach for PSCs, where NiOX, SAM ((E)-3-(4-(bis(4-methoxyphenyl)amino)phenyl)acrylic acid, abbreviated as MPTCA) wetting agent (2-phenylethylamine hydroiodide, known PEAI) are employed hole-transport materials (HTMs). This NiOX/MPTCA/PEAI composite layer is uniform has good properties, which enables formation high-quality film, effectively minimizing defects that typically occur at buried interface. An outstanding champion efficiency 24.74% was obtained devices, followed by enhanced with an average power conversion (PCE) 24.13 ± 0.26%, notably higher than (22.73 0.62%) pristine MPTCA-based PSCs. More importantly, composited HTL-based devices without encapsulation demonstrated remarkable stability, decrease less 10% initial after 500 h continuous light soaking.

Abstract In addition to the heterojunction layer, interfacial layers also determine performance of organic solar cells (OSCs) owing their great role in promoting charge extraction. Herein, study explores use rarely reported polyaniline (PANI)‐derived polymers as self‐assembled hole‐transporting layer (HTL) OSCs. It is observed that tailoring either spacer groups or polymerization sites can greatly affect material aggregation and thus OSC performance. Specifically, polymer with phenyl (36‐Ph‐PANI) largely outperforms alkyl linkers, which ascribed enhanced aspect ratio dipole moment former molecule contributes substrate coverage hole Moreover, linking PANI carbazole at 2,7‐sites much inferior than 3,6‐positions, attributing higher mobility latter induced by formation radical cation. The combined merits 36‐Ph‐PANI, including high transmittance, appropriate doping, efficient extraction, enable a decent efficiency 15.08% This work provides subtle strategy for developing self‐assemble into monolayers, paving way more stable

Azulene has been attracting much attention as a charge transfer material in organic electronics due to its inherent large dipole moment and small band gap, but application perovskite solar cells (PSCs) is very limited. Herein, azulene was applied the core acceptor for hole transport materials (HTMs), two molecules named Azu-Py-DF Azu-Py-OMeTPA were designed synthesized, which 4-pyridyl introduced on 6-position of 1,3-substituted adjust energy levels. The different spatial orientations pyridine improve solubility reduce crystallinity material, conducive creating thin film morphology. exhibited good electron mobility compared with standard Spiro-OMeTAD. Applied an HTM PSCs, Azu-Py-OMeTPA-based device achieved power conversion efficiency (PCE) 18.10%, higher than that unsubstituted counterpart. Nevertheless, anticipated passivation effect group diminished electron-deficient nature azulene’s seven-membered ring. These results demonstrate optimizing structure azulene-based HTMs can significantly alter molecular structure, formation properties, delocalization characteristics transport, lead improved performance, providing insights future design novel HTMs.
