Self-assembled monolayers (SAMs) have been widely employed as the bottom-contact hole-selective layer (HSL) in inverted perovskite solar cells (PSCs). Besides manipulating electrical properties, molecularly engineering SAM provides an opportunity to modulate buried interface. Here, we successfully introduced Lewis-basic oxygen and sulfur heteroatoms through rational molecular design of asymmetric SAMs obtain two novel multifunctional SAMs, CbzBF CbzBT. Detailed characterization single-crystal structures device interfaces shows that enhanced packing, more effective ITO work function adjustment, interface passivation were achieved. Consequently, champion PSC employing CbzBT showed excellent power conversion efficiency (PCE) 24.0% with a high fill factor 84.41% improved stability. This demonstrates feasibility introducing defect-passivating heterocyclic groups into molecules help passivate interfacial defects PSCs.

P-i-n geometry perovskite solar cells (PSCs) offer simplified fabrication, greater amenability to charge extraction layers, and low-temperature processing over n-i-p counterparts. Self-assembled monolayers (SAMs) can enhance the performance of p-i-n PSCs but ultrathin SAMs be thermally unstable. We report a robust hole-selective layer comprised nickel oxide (NiOx) nanoparticle film with surface-anchored (4-(3,11-dimethoxy-7H-dibenzo[c,g]carbazol-7-yl)butyl)phosphonic acid (MeO-4PADBC) SAM that improve stabilize NiOx/perovskite interface. The energetic alignment favorable contact binding between NiOx/MeO-4PADBC reduced voltage deficit various compositions led strong interface toughening effects under thermal stress. resulting 1.53-electron-volt devices achieved 25.6% certified power conversion efficiency maintained >90% their initial after continuously operating at 65 degrees Celsius for 1200 hours 1-sun illumination.

Interfacial layers (ILs) are prerequisites to form the selective charge transport for high-performance organic photovoltaics (OPVs) but mostly result in considerable parasitic absorption loss. Trimming ILs down a mono-molecular level via self-assembled monolayer is an effective strategy mitigate However, such suffers from inferior electrical contact with low surface coverage on rough surfaces and poor producibility. To address these issues, here, interlayer (SAI) developed, which involves thin layer of 2-6 nm full substrate both covalent van der Waals bonds by using molecule 2-(9H-carbazol-9-yl) (2PACz). Via facile spin coating without further rinsing annealing process, it not only optimizes optical properties OPVs, enables world-record efficiency 20.17% (19.79% certified) also simplifies tedious processing procedure. Moreover, SAI especially useful improving absorbing selectivity semi-transparent record light utilization 5.34%. This work provides optimize OPVs solar window applications.
