Nonetheless, the computational space of perovskites is quite large and first-principles is expensive, and this makes systematic optimization of materials a challenging problem. This paper presents a unified multiscale system that entails the implementation of density functional theory (DFT), machine learning (ML), and device-level simulation to hasten the search and development of high-performance perovskite solar cell materials. Physically significant descriptors are generated through DFT calculations such as structural parameters, electronic bandgaps, formation energies, and properties of defect-related characteristics. The descriptors are utilized to train the supervised ML models that can predict the important material and photovoltaic performance indicators with high accuracy at a rapid rate. Predictions of the ML are then combined with practicing simulations of the device to assess open-circuit voltage, short-circuit current density, fill factor, and power conversion efficiency. The findings show that there are good correlations among defect tolerance, bandgap optimization, and photovoltaic performance with defect suppression being a leading channel of increasing the efficiency. The current DFT-ML scheme consumes much less computational power; however, still has physical interpretability, and can offer efficient and predictive solution to perovskite material screening as well as solar cell design scaling.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"16 4","pages":""},"PeriodicalIF":3.674,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148750532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural characterization revealed significant plasma-induced modifications, including changes in functional groups, increased oxygen-containing species, and improved surface activation. Morphological analyses confirmed successful nano-transformation through particle size reduction, improved particle dispersion, and decreased aggregation. AFM measurements showed a reduction in the average particle size from 123.7 nm to 70.7 nm after plasma treatment.

These physicochemical modifications resulted in improved antibacterial activity against both Escherichia coli and Staphylococcus aureus, with inhibition zones increasing from 16 to 21 mm and from 17 to 22 mm, respectively. The enhanced antibacterial performance is attributed to the combined effects of nanoscale particle size, increased surface activity, and plasma-induced surface functionalization.

The device is fabricated by incorporating solution-processed CuSbSe₂ microrods with several-layer MoS₂ film that are assembled into a Type-II p–n heterojunction structure to facilitate the efficient photon absorption, charge separation and fast charge transport. The hybrid photodetector showed a high peak responsivity of 1.08 ± 0.09 AW⁻¹ and an external quantum efficiency of 86 ± 7% when illuminated by 450 nm light. To our knowledge, this is one of the highest responsivity values recorded for CuSbSe₂ based photodetectors, and is about 10 times greater than that of previously reported CuSbSe₂ single-crystal devices when tested using the same optoelectronic conditions. The response curve was found to be broadband (300–1300 nm) with measurable response even close to the cutoff wavelength (1280 ± 20 nm). The temporal rise and decay times were measured to be 0.48 ± 0.05 and 0.52 ± 0.06 ms, respectively, which were considered as the fast temporal response of the device. Furthermore, the dark current is less than 5 nA, and the noise equivalent power is about <span>(:1times:{10}^{-13}text{hspace{0.17em}W}/sqrt{text{Hz}})</span>, indicating the photodetector has a high sensitivity and low-power operation. The enhanced properties are believed to be due to the CuSbSe₂/MoS₂ interface band alignment and the built-in electric field which prevents recombination and increases carrier extraction.

Three structural regimes were considered: 0D quantum dots, 1D nanowires/nanotubes, and 2D layered nanosheets. The results show that the band gap decreases with increasing particle size, nanowire diameter, or layer number, reflecting the weakening of quantum confinement and the transition toward bulk-like behavior. In contrast, the refractive index and reflectivity increase with structural size because of the inverse relationship between band gap and optical polarizability. PdSe₂ generally exhibits larger band-gap values, whereas InSb shows relatively higher refractive-index and reflectivity values in larger structures due to its narrow bulk band gap. The model predictions show reasonable agreement with available experimental and theoretical data, particularly for band-gap trends, while deviations in refractive index and reflectivity are attributed to the empirical nature of the Moss and Fresnel relations and the absence of wavelength-dependent, anisotropic, and surface-related effects. The results demonstrate that the cohesive-energy approach can provide a useful comparative framework for describing dimensionality-dependent optical trends in semiconductor nanostructures.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"16 4","pages":""},"PeriodicalIF":3.674,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
