“…The rate of absorption is significantly influenced by the band gap and photon energy. Figure . 3 shows how the optical absorption coefficient (α) for the Ag2Se annealing sheets fluctuates with photon energy while keeping in mind the equations [20]. This can be written: where (A) is the film's absorbance, and (t) is the thickness of the film.…”

This survey investigates the thermal evaporation of Ag2Se on glass substrates at various thermalannealing temperatures (300, 348, 398, and 448) °K. To ascertain the effect of annealingtemperature on the structural, surface morphology, and optical properties of Ag2Se films,investigations and research were carried out. The crystal structure of the film was described by Xraydiffractionandothermethods.ThephysicalstructureandcharacteristicsoftheAg2Sethinfilms wereexaminedusingX-rayandatomicforcemicroscopy(AFM)basedtechniques.TheAg2Se films surface morphology was examined by AFM techniques; the investigation gave averagediameter, surface roughness, and grain size mutation values with increasing annealing temperature(75.74 nm–96.36 nm). Additionally, With various variations to the nominal values, the absorbanceand transmittance spectra are further studied and reported in accordance with the wavelength rangeof (400-1100) nm. The findings indicate that the sample highest absorbance value was attained ata temperature treatment of 448 K, whereas the sample highest transmittance was at a temperaturetreatment of 300 K. According to the results, direct transitions were permitted in the under-reviewthin films at optical energies of (2.15, 1.85, 1.75, and 1.7) eV, respectively

“…Metal nanoparticles' color and optical characteristics are caused by surface plasma resonance (SPR), a collective longitudinal excitation of conduction electrons on the nanoparticles' surface [7]. The primary goal of this study is to fabricated (n-WO 3 /p-Si) heterojunction with doped tungsten oxide films in various concentrations of gold nanoparticles (0, 0.04, 0.08 M) by using the spray pyrolysis technique, which is one of the processes used to produce and prepare thin films of tungsten trioxide [8][9][10][11][12][13][14][15], as well as to examine the structural, optical, and surface characteristics of the prepared samples.…”

At a substrate temperature of 320 o C, a chemical spray pyrolysis approach was applied. to create tungsten oxide thin films on glass substrates with varying Au nanoparticle doping concentrations (0, 0.04 and 0.08 M) that have a thickness of roughly 250 nm. Investigated were the structural and optical characteristics. The films were amorphous to the pure films at the substrate temperature (320 °C), according to X-ray diffraction and remain so even after adding GNPs, because the WO3 structure is amorphous in all samples, whereas the cubic structure of the gold nanoparticles. The morphology of the films was examined using atomic force microscopy (AFM), which showed a decrease in the grain size of the films doped with gold compared to the thin films before the doping process. a UV-Vis spectrophotometer was used to examine the membranes' optical characteristics between the wavelengths of (300-1000) nm. was the optical energy gap of the films (3.23) eV for tungsten oxide film and decreased after adding nanoscale gold to (3.04, 2.95) eV for films doped with different proportions of Au NPs (0.04, 0.08 M), respectively. Hall testing confirms that with 8 (mM) Gold (Au) doping, WO3 material of the n type was obtained with a maximum carrier mobility of 219.92(cm2 /Vs) and conductivity of 6.52 (Ω.cm)-1 . The I-V characteristics of the photovoltaic formed under illumination were determined by measuring the incident power density (100 mW/cm2 ) at varied Au doping levels.
