The calculated elastic properties confirm the mechanical stability and ductile behavior of both compounds.

In this work, these challenges are addressed through an integrated device design combining hydrothermally grown rutile TiO₂ nanorod arrays, PbS QDs with Cd-based surface passivation, and mild atmospheric-pressure argon plasma surface engineering. The vertically aligned TiO₂ nanorods serve as efficient electron-transporting scaffolds, with their geometry controlled by the hydrothermal growth duration, providing continuous carrier extraction pathways and a high interfacial contact area. The Cd-based passivation, introduced via a post-synthetic cation exchange protocol, is employed to suppress surface defects and improve environmental stability. As a key innovation, a low-power atmospheric plasma treatment is utilized to precisely tailor the surface chemistry and interfacial energetics of the QD films at room temperature without inducing structural degradation. Structural and spectroscopic characterizations support the successful formation of the TiO₂/PbS hybrid architecture, although the ultra-small crystallite size and thin loading of the QD layer yield no distinct PbS diffraction peaks in XRD, and direct particle size distributions remain unverified in the absence of TEM/HRTEM imaging. Device-level characterization demonstrates that the plasma-treated TiO₂/PbS QD heterojunction solar cell achieves an initial power conversion efficiency (PCE) of approximately 10.8%, representing a notable improvement over the 9.6% obtained for the pristine control device. Furthermore, the plasma-treated device exhibits enhanced ambient stability, retaining approximately 80.5% of its initial performance (from 10.8% to 8.7%) over an 11-day testing period, compared to a 72.9% retention (from 9.6% to 7.0%) for the pristine device. This performance enhancement is corroborated by electroluminescence analysis showing significant quenching of radiative recombination, indicating more efficient charge separation and extraction at the heterojunction interface. This work highlights room-temperature plasma-assisted surface engineering as an effective and scalable strategy to overcome transport and interfacial limitations in near-infrared quantum dot solar cells.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"58 11","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148986694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To provide physical insight into the resonant behavior, an equivalent circuit model is developed and validated against full-wave electromagnetic simulations.

These derivatives are being developed for next-generation organic electronics. Quantum chemical simulations indicate that this change lowers LUMO level, reducing the electronic bandgap from 4.42 eV in ZAU1 to 4.05 eV in ZAU3. While HOMO remains in the central rigid core for both molecules, ZAU3’s LUMO shifts to the ester arms, significantly altering the spatial structure. This reduces the electron exchange integral, establishing conditions for a small singlet-triplet energy gap in thermally activated delayed fluorescence (TADF) host architectures. However, this change decreases the vertical transition probability (f = 0.0653; LHE = 14.0%) compared to ZAU1 (f = 0.1095; LHE = 22.3%). Analysis using Marcus electron-transfer theory shows that ZAU3 achieves better charge-transport kinetics in the solid-state, with low hole and electron reorganization energies by limiting structural relaxation. Moreover, ester functionalization alters the adiabatic ionization potential (IP_a = 5.86 eV) and electron affinity (EA_a = 1.79 eV), reducing interfacial injection barriers. Molecular electrostatic potential (MEP) surfaces reveal a substantial increase in ZAU3’s permanent dipole moment (3.87 D vs. 1.62 D for ZAU1). Additionally, 2D Reduced Density Gradient (RDG) and Non-Covalent Interaction (NCI) plots verify that the extended molecular structures are stabilized by widespread weak van der Waals interactions. This intricate balance between spatial orbital separation and internal reorganization is crucial, positioning ZAU1 as ideal for emissive layers or light harvesting. At the same time, ZAU3 is suitable as a high-mobility charge-transport matrix or ambipolar interlayer and a potential TADF host.
