“…Soda lime glass substrates are used to deposit pure and Zn:CuO thin films using the chemical spray pyrolysis method (HOLMARC). 0.05 M of pristine solution is prepared by taking copper chloride dihydrate along with deionized water (75%) and ethanol (25%), for other weight percentages (1,3,5) of Zn doped CuO solutions, zinc acetate dihydrate is added. The solutions prepared are stirred using a magnetic stirrer for about 20 min.…”

“…Various applications of CuO have been reported in the field of semiconductor electronics ranging from photovoltaics, gas sensing, and photocatalysts [2]. Many researchers in the past decades have studied the effects of doping different elements like In [3], Fe [4], Co [5], Mn [6], Zn [7], and Ag [8] on cupric oxide. Kose et al [3] reported that Indium doping increased the bandgap of CuO and decreased its roughness.…”

Nanostructured pure and Zn doped CuO thin films were deposited on a glass substrate at 400 °C using the chemical spray pyrolysis method. The fabricated thin films were characterized to study the compositional, structural, morphological, optical and electrical properties. X-ray diffraction spectra show the polycrystalline nature of the sample and confirm the monoclinic phase of copper oxide. Raman analysis further confirms the absence of cuprous oxide phases and impurities. High absorbance in the visible region was observed for the films with bandgap values ranging from 1.7–2.0 eV. A near-band edge emission peak in the red region is recorded in the photoluminescence spectra. Uniformly distributed nanoparticles are observed in SEM images. Hall effect measurements indicate p-type conductivity and 5% Zn doped copper oxide showed the highest conductivity and carrier concentration. The non-linear absorption coefficient (β eff) of the samples was obtained with the help of z-scan method with a Helium-Neon laser under the CW regime. Zn doping results in an increase in nonlinear absorption, supporting the use of Zn:CuO for optoelectronic devices.

“…In this work, the feasibility of preparing FeS2 thin film is studied to fabricate low-cost photocell by spray pyrolysis technique [10,11]. The angle of the nozzle in our CSP system is set at 45° to decrease the defects and to obtain smooth and more homogenous thin films [12]. Many research articles showed important applications of semiconducting thin films prepared by CSP in heterojunction devices [13][14][15] 2.…”

In this work, the physical properties of iron sulfide (FeS2) thin films deposited by the chemical spray-pyrolysis (CSP) technique were studied. The thin films are deposited on glass substrates at 200 o C, using FeCl3 salt with thiourea (NH2)2CS as precursors. Structural analysis of X-Ray diffraction manifested that the thin films contain two phases: Marcasite and Pyrite in planes ( 110), ( 111) at angles 2θ =26.3°, 2θ =28.3° respectively. Optical properties analysis showed that the prepared iron sulfide thin-films were highly absorbing in the UV-Visible range and the absorption coefficient was in the range of 1.6x10 5 cm-1 with a relatively low resistivity of about 0.49 (Ω.cm). The calculated activation energy (Ea) was 0.024 eV and the bandgap value was 2.45 eV. Moreover, the FeS2 thin films were also deposited on (CdO) to fabricate a heterojunction photocell. In conclusion, there is the feasibility of preparing low-cost and highly absorbing iron sulfide (FeS2) thin films for optoelectronic applications with acceptable homogeneity using the spray-pyrolysis technique.

“…It is well-known that both the chemical and the physical properties of oxide thin films are greatly dependent on the morphology and structures of the prepared sample [16]. As a result various CuO nanostructure types have been prepared such as nanoparticles [17], honeycombs [18], nanorods [19,20], nanowires [21] and nanourchins [22] using various techniques such as hydrothermal [23], sputtering 2 [24] thermal oxidation of Cu foil [25], Spraying Pyrolysis [26], and a chemical bath deposition (CBD) method [27] [28]. There are several benefits to the CBD technique, including that the simple equipment, such as a hot plate with a magnetic stirrer, is sufficient for the required sedimentation.…”

In this work, copper oxide (CuO) thinfilms are prepared by chemical bath deposition technique (CBD). The films are investigated with respect to annealing temperature and molar concentration. According to XRD analysis, all the prepared thin films were polycrystalline with monoclinic structures and almost oriented at the planes (002) and (111). FESEM analysis revealed rod-like shapes. The observed bandgap value of copper oxide thin films ranged from 1.65 eV to 1.59 eV. CuO film exhibits high absorption in the visible spectrum. This activity is particularly intriguing in terms of the use of CuO as an absorber layer in solar cells. Moreover, the electrical conductivity and the activation energy of CuO were found to be influenced by the molar concentration and annealing temperatures. These findings show that CuO films prepared by the CBD method can be used to fabricate optoelectronic devices.
