“…The more optical absorbance can reason major losses inside the thin film material. These found results are good agreement to other research works on absorber materials[39,47]. The values of optical parameters including: absorption coefficient, refractive index, extinction coefficient, real dielectric constant and imaginary dielectric constant in wavelength λ 800 nm are tabulated inTable 3.…”

Quaternary semiconductor Cu2NiSnS4 thin film was made by the sol-gel method associated to dip-coating technique on ordinary glass substrates. In this paper, we have studied the impact of dip-coating cycle at different cycles: 4, 5 and 6 on the structural, compositional, morphological, optical and electrical characteristics. CNTS thin films have been analyzed by various characterization techniques including: X-ray diffractometer (XRD), Raman measurements, scanning electron microscope (SEM), energy dispersive X-ray spectroscope (EDS), UV-visible spectroscopy and four-point probe method. XRD spectra demonstrated the formation of cubic Cu2NiSnS4 with privileged orientation at (111) plane. Crystallite size of cubic CNTS thin films increase with from 6.30 to 9.52 with dip-coating cycle augmented. Raman scattering confirmed the existence of CNTS thin films by Raman vibrational mode positioned at 332 cm− 1. EDS investigations showed near-stoichiometry of CNTS sample deposited at 5 cycles. Scanning electron microscope showed uniform surface morphologies without any crack. UV-visible spectroscopy indicated that the optical absorption values are larger than 104 cm− 1, Estimated band gap energy of CNTS absorber layers decrease from 1.64 to 1.5 eV with dip-coating cycle increased. The electrical conductivity of CNTS thin films increase from 0.19 to 4.16 (Ω cm)-1. These characteristics are suitable for solar cells applications.

“…[ [22][23] Davis and Motto developed the following mathematical formula to describe the absorption coefficient as a function of both the photon energy hν and the direct/indirect optical band gap Eopt. Where ξ = 2 for allowing direct transitions and ξ = ½ for allowing indirect transitions [24][25]. The optical band gaps for both direct and indirect transitions can be obtained by plotting (αhν) 2 and (αhν) 1/2 verses hν respectively, then extrapolate the linear portion to intersect the horizontal axis (hν) at point represents the optical band gap [26][27], as seen in the figure 8 and figure 9.…”

Some bismuth-borate oxide glass' samples were prepared by the fast quenching method, where B2O3 was replaced with equal concentrations of ZnO and CaO. X-ray diffraction (XRD) was used to examine the internal structure and Fourier transform infrared (FTIR) to identify building units and bonds throughout the studied structural matrices. XRD showed that all samples have short range order structural nature, while FTIR demonstrated some of Zn2+ acted as glass network formers and all Bi3+ acted as glass. UV-visible measurements and calculations showed a decreasing in the energy band gap from 3.83 eV to 1.73 eV with decreasing B2O3 content. Also with decreasing B2O3 content, both real refractive index and metallization factor decreased from 3.1 to 1.9 and from 0.56 to 0.71, respectively. For the studied glass' samples, density and molar volume showed inverted behaviors, where the density decreased while the molar volume increases with decreasing B2O3.

“…[25] The bands near 340 cm À 1 have been attributes to E 1 (LO) that represent a Raman mode for chalcopyrite ordering. [26] A band attributed to CuS impurity phase is observed at 470 cm À 1 [24] and is clear in the spectra of the non-pulse deposited film and in the film double pulse electrodeposited at θ = 50 %. Although X-ray diffractogram for CuGaS 2 film deposited with θ = 33 % present peaks of CuS impurity, the Raman spectra does not present the band at 470 cm À 1 .…”

CuGaS2 photovoltaic thin films were prepared on fluorine‐doped tin oxide substrates using a double‐pulse electrodeposition approach. The environmentally friendly one‐step electrochemical deposition was performed under aqueous medium conditions, using Na2S2O3 as the sulfur source, with no additional step of sulfurization. The composition of CuGaS2 films was improved in double‐pulse electrodeposition mode. At lower duty cycle, θ=25 %, with the largest applied anodic potential time, highly pure and stoichiometric CuGaS2 films were electrodeposited through a one‐step method.
