“…The transmittance values are reduced by increasing the temperature of annealing due to an increase in absorbance. It is also noted that the higher permeability values are shifted towards the larger wavelength when the thickness increases ,this is consistent with the sources [9,10,11]. Fig.…”

“…3 is shown the spectra of reflectance for AIT thin films. In the range of (550 -650) nm the reflectance of AgInTe 2 the reflection decreases with the temperature and increases with the wavelength [10,11] ,but at (T=473K) refers to the susceptibility of this different material to change its reflection by wavelength, due to the correlation of reflectivity to the change of absorbance and permeability within these wavelengths The shift of transmittance and reflectance refer to that regard to the change in the crystalline properties of the film and decrease with wavelength from the range of (800 to 1100) nm [9]. The shift towards higher or to lower energies depends on the method of film preparation [11].…”

In this study,the nanoparticles of zinc oxide were readily prepared through Hydrothermal process by using zinc nitrate hexahydrate, and Sodium hydroxide as aprecursors. The surface topology, and crystalline structure of prepared ZnO nanoparticles were studied. X-ray diffraction (XRD) revealed that the prepared ZnO nano particles is highly crystalline, having (wurtzite) crystal structure. The optical analysis by UV–vis showed that these ZnO nano particles have considerable blue shift in the optical band gap energy (Eg = 4.9eV), and this may be to the quantum confinement effect of nano particles. The FT-IR results shows the existence of OH, COO, H2O groups the characteristic vibrational modes of Zn–O were identified. and AFM analysis showed that the diameters of the ZnO particles is in ananometer range of (70-74)nm. http://dx.doi.org/10.25130/tjps.24.2019.052

AgInTe2 (AIT) thin films had been prepared by the used technique of vacuum thermal evaporation, with thickness 300 nm, the deposition rate 1.7 ±0.1 nm/sec on a glass substrate at room temperature and pressure (10-5) mbar Heat treatment was performed in the range (473-673) K for samples. The AIT thin films optical properties (absorption coefficient, index of refractive, extinction coefficient, real and imaginary dielectric constant) were studied by determination using measurement absorption and transmission spectra. The results showed they are wide applications such as photovoltaic electronic applications and photovoltaic applications.

“…In this design, p + -type AgInTe 2 has been employed to perform double role such as bottom absorber and back surface field (BSF) layer. Because of its high absorption coefficient (α) i.e sub-band gap absorption in the longer wavelength region, it is an efficient material as bottom absorber layer to absorb longer wavelength photons ( El-Korashy et al., 1999 ; Vaidhyanathan et al., 1983 ). AgInTe 2 has electron affinity and ionization potential of 3.6 eV and 4.76 eV, respectively making it a suitable candidate to form a pp + junction with Sb 2 Se 3 .…”
