Abstract Effective passivation of defects at the buried interface between perovskite absorber and hole‐selective layer (HSL) is crucial for achieving high performance in inverted solar cells (PSCs). Additionally, HSL needs to possess compact molecular packing intrinsic photo‐ thermo‐stability ensure long‐term operation devices. In this study, a novel MeO‐BTBT‐based self‐assembled monolayer (SAM) reported serve as an efficient PSCs. Compared well‐established carbazole‐containing SAM MeO‐2PACz, MeO‐BTBT has flat more extended conjugation with large atomic radius sulfur atom. These induce stronger intermolecular interactions enable ordered be formed on indium–tin oxide (ITO) substrates. Meanwhile, atoms can coordinate Pb 2+ ions passivate absorber.

Abstract Perovskite solar cells (PSCs) have attracted much attention due to their low-cost fabrication and high power conversion efficiency (PCE). However, the long-term stability issues of PSCs remain a significant bottleneck impeding commercialization. Inverted with p-i-n architecture are being actively researched concurrent good decent efficiency. In particular, PCE inverted has improved significantly in recent years is now almost approaching that n-i-p PSCs. This review summarizes progress development high-efficiency PSCs, including perovskite compositions, methods, counter electrode materials (CEMs).

Carbazole-derived self-assembled monolayers (SAMs) are promising hole-selective materials for inverted perovskite solar cells (PSCs). However, they often possess small dipoles which prohibit them from effectively modulating the workfunction of ITO substrate, limiting PSC photovoltage. Moreover, their properties can be drastically affected by even subtle structural modifications, undermining final performance. Here, we designed two carbazole-derived SAMs, CbzPh and CbzNaph through asymmetric or helical π-expansion improved molecular dipole moment strengthened π-π interaction. The π-expanded has largest dipole, forming densely packed ordered monolayer, facilitated highly assembly observed in its π-scaffold's single crystal. These synergistically modulate crystallization atop tune workfunction. Consequently, champion employing showed an excellent 24.1 % efficiency stability.

Interfacial engineering has long been a vital means of improving thin-film device performance, especially for organic electronics, perovskites, and hybrid devices. It greatly facilitates the fabrication performance solution-processed devices, including field effect transistors (OFETs), solar cells (OSCs), perovskite (PVSCs), light-emitting diodes (OLEDs). However, due to limitation traditional interfacial materials, further progress these devices is hampered particularly in terms stability, flexibility, sensitivity. The deadlock gradually broken through development self-assembled monolayers (SAMs), which possess distinct benefits transparency, diversity, sensitivity, selectivity, surface passivation ability. In this review, we first showed evolution SAMs, elucidating their working mechanisms structure–property relationships by assessing wide range SAM materials reported date.

Power conversion efficiencies (PCEs) of inverted perovskite solar cells (PSCs) have been improved by the use a self-assembled monolayer (SAM) hole transport layer. Long-term stability PSCs requires keeping SAM compact under layer during operation. We found that strong polar solvents in precursor desorb if it is anchored on substrates hydrogen-bonded, rather than covalently bonded, hydroxyl groups. used atomic-layer deposition to create an indium tin oxide substrate with fully covalent hydroxyl-covered surface for anchoring, as well trimethoxysilane group exhibited tridentate anchoring substrate.

Self-assembled monolayers (SAMs) are widely employed as effective hole-selective layers (HSLs) in inverted perovskite solar cells (PSCs). However, most SAM molecules amphiphilic nature and tend to form micelles the commonly used alcoholic processing solvents. This introduces an extra energetic barrier disassemble during binding of on substrate surface, limiting formation a compact SAM. To alleviate this problem for achieving optimal growth, co-solvent strategy carbazole-based solution is developed. effectively increases critical micelle concentration be above enhances reactivity phosphonic acid anchoring group allow densely packed SAMs formed indium tin oxide. Consequently, PSCs derived from using MeO-2PACz, 2PACz, CbzNaph HSLs show universally improved performance, with SAM-derived device champion efficiency 24.98% stability.

Hole-collecting monolayers have drawn attention in perovskite solar cell research due to their ease of processing, high performance, and good durability. Since molecules the hole-collecting monolayer are typically composed functionalized π-conjugated structures, hole extraction is expected be more efficient when π-cores oriented face-on with respect adjacent surfaces. However, strategies for reliably controlling molecular orientation remain elusive. In this work, multiple phosphonic acid anchoring groups were used control a series triazatruxene derivatives chemisorbed on transparent conducting oxide electrode surface. Using infrared reflection absorption spectroscopy metastable atom electron spectroscopy, we found that multipodal align surface, while monopodal counterpart adopts tilted configuration. The was facilitate extraction, leading inverted cells enhanced stability high-power conversion efficiencies up 23.0%.
