Effect of the immersion in CdCl2 and annealing on physical properties of CdS:F films grown by CBD

Growth of CdO films from CdO2 films by chemical bath deposition: Influence of the concentration of cadmium precursor

“…4a) shows the transmittance spectra of as-grown CdO 2 films. The CD-01 and CD-02 samples present absorption of light in the wavelength region ≥ 400 nm, which can be attributed to crystalline defects, that are responsible of the reduction of transmittance [5]. The CD-03 sample has a high transmittance in the visible region (>70%) and the spectrum presents an absorption edge practically vertical, indicating a good crystalline quality of the sample (in agreement with the XRD results).…”

Influence of fluorine doping on the microstructure, optical and electrical properties of SnO2 nanoparticles

“…The direct band gap is determined using this equation when the straight portion of the (αhν) 2 against hν plot is extrapolated to intersect the energy axis at α = 0. Figure 5 shows the plots of (αhν) 2 versus photon energy hν for FTO nanoparticles with [38,39]. The band gap energies of the SnO 2 materials show a decrease with the increase of doping concentration (Fig.…”

Physical and Dielectric Properties of Ni-Doped In2S3 Powders for Optical Windows in Thin Film Solar Cells

“…In addition, In 2 S 3 is an n-type semiconductor that crystallizes at atmospheric pressure in three polymorphic forms (named α, β, and γ) as a function of temperature [ 1 ]. These remarkable characteristics of In 2 S 3 combined with its eco-friendly nature [ 2 , 3 ] make it well-suited for use in a variety of applications that are fabricated by different processing methods [ 4 , 5 , 6 , 7 ]. In 2 S 3 is generally used in photovoltaic applications [ 8 ], semiconductor batteries [ 9 ], and photoelectrochemical cells [ 10 , 11 ].…”
