Aluminum (Al) nanoparticles with rutile titanium oxide (TiO₂) nanoparticle thin films are fabricated on Fluorine Tin Oxide (FTO) glass substrates by nanosecond pulsed fiber laser deposition (PLD) to be used as a plasmonic electron transport layer (ETL) in perovskite solar cell (PSC). The effect of various pulsed fiber laser parameters on the structural, optical, and surface morphology on Al/TiO₂ films is extensively examined utilizing a variety of measurement techniques; X-ray diffraction (XRD), Ultraviolet–visible (UV–Vis) spectroscopy, Field emission scanning electron microscopy (FE-SEM) and Atomic Force microscope (AFM). XRD demonstrates that Al/TiO₂ thin films has a mixed phase (anatase/rutile). The minimum average crystallite size of Al/TiO₂ thin films deposited at (2 W - 40 kHz) is (19.8 nm). The absorption spectrum of the deposited Al/TiO₂ thin film at (10 W - 20 kHz) shows a red-shifted absorption peak at 316 nm, while 307 nm is detected at (2 W - 20 kHz). As the pulse repetition rate rise (40, 60 kHz), a new absorption peak in the UV spectral region at 341 nm was observed. FESEM images demonstrate the nanoparticles’ uniformity and polycrystalline nature. The shape of nanoparticles becomes more uniform and smaller size when the power increases. The minimum power required to get a uniform film is 0.8 W nm with suitable thickness of 398.8 obtained by fitting the thickness values curve of Al/TiO₂ thin films. The elemental analysis examined by the EDX spectrum of Al/TiO₂ thin films consists of oxygen, aluminum, and titanium. AFM images reveal a granular microstructure, and a flat texture, with the lowest surface roughness. The obtained results from the current study indicate that the structural, optical, and morphological properties can be controlled by varying the fiber laser parameters to deposit an efficient plasmonic Al/TiO₂ thin films could be used as an electron transport layer which open new trends to improve the performance of perovskite solar cell.</div></div>","PeriodicalId":19513,"journal":{"name":"Optik","volume":"334 ","pages":"Article 172387"},"PeriodicalIF":3.1,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed FRSA includes seven ideal switches (labeled w1–w7) positioned along the longitudinal slot, facilitating its reconfigurable functionality. By toggling these switches ON and OFF, the antenna operates in nine different modes. A single-layer metasurface reflector (MSR) was integrated below the FRSA to enhance the antenna's gain and directivity. The proposed MSR consists of a 2 × 2 array with a unit cell (UC) size of 18.25 mm× 15.025 mm, optimized to produce a center-operating frequency. The MSR achieves a stopband transmission coefficient (S21) below −10 dB and exhibits a linear reflection phase within the bandwidth of 3.30 ─ 5.96 GHz, nearly encompasses the FRSA frequency tuning range 3.05 – 5.16 GHz. Combining the FRSA and MSR significantly enhanced performance. The gain improved by 2.49 dB overall, rising from 3.14 dB to 5.63 dB in the lower band and from 5.25 dB to 5.38 dB in the upper band. Varying the FRSA and MSR gap enabled more gain optimization, enabling the gain to range from 3.93 dB to 6.09 dB. The FRSA with MSR covers an operating frequency range of 3.05 GHz to 5.24 GHz and supports operation at 3.05 GHz, 3.38 GHz, 3.98 GHz, 4.06 GHz, 4.34 GHz, 4.70 GHz, 4.74 GHz, 4.80 GHz, and 5.24 GHz. The proposed FRSA with MSR maintains a compact configuration, as the MSR's size matches the antenna's dimensions (0.38 λ₀ × 0.31 λ₀). The gap between the MSR and the antenna is only 20 mm (0.204 λ₀), where the wavelength (λ₀) corresponds to the minimum operating frequency of 3.05 GHz in free space. A prototype of the FRSA with MSR was fabricated and its performance was validated through measurements.
