“…[ 26,27 ] In addition, two strong Cu 2+ satellite peaks at 943 and 962.5 eV are present, further confirming that Cu is present in the oxidation state of +2. Moreover, the presence of oxygen in the film was confirmed by the detection of a peak located at 531.1 eV which corresponds to the O 1s core shell [ 28 ] (Figure 1b). Thus, it can be concluded that as‐deposited IL is cupric oxide (CuO).…”

Herein, it is demonstrated that incorporating ultrathin p‐type cupric oxide (CuO) enhances the performance and stability of solution‐processed Cu2(Zn0.6Cd0.4)SnS4 (CZCTS)/CdS thin film solar cells. In sol–gel CZCTS/CdS thin film solar cells, nanoscale CuO films (4–32 nm) are deposited on top of molybdenum (Mo) by magnetron sputtering and this is used as an intermediate layer (IL). The CuO IL thickness has a significant effect on the short‐circuit current density (JSC) in CZCTS/CdS solar cell devices. As a result, a maximum power conversion efficiency (PCE) of 10.77% is measured for the optimized device with 4 nm CuO compared with 10.03% for the reference device without a CuO layer. Furthermore, the stability of the devices is enhanced significantly by incorporating the CuO IL. This work demonstrates that through proper design of the CuO IL thickness, both the back interface quality and optical property of the CZCTS absorber can be tuned to enhance the device performance.

“…On the other hand, no peaks related to cuprite Cu 2 O or Ni phases (nickel oxide NiO) were detected with raise of Nickel concentration; which concludes that Ni +2 ions would have effectively replaced Cu +2 ions without changing the crystal structure of the CuO parent compound (wook Ha et al, 2018;Basith et al, 2014). This can be due to to the similar ionic radii of Cu +2 and Ni +2 (Cu +2 = 0.73 Å and Ni +2 = 0.70 Å) thus facilitating the above substitution of Cu +2 by Ni +2 (Dolai et al, 2019). This implies that the monoclinic structure of CuO is not distorted by Ni doping.…”

“…Use of a properly low cost and strongly water-soluble copper chloride dehydrate (CuCl 2 .2H 2 O) precursor can provide crystalline type of CuO films in as-deposited status. Ni is chosen a dopant for CuO because the ionic radius of Ni +2 is 0.70 Å which is quite comparable with that of Cu +2 (0.73 Å) (Dolai et al, 2019;Yin et al, 2020;Shannon, 1976). An appropriate n-type material will be required with the CuO absorber layer in order to construct a single p-n junction.…”

Whereas solar photovoltaic cells are promising for proper power production,their wide deployment is hampered by production costs, material availability and toxicity. One of these materials is CuO, which has great chemical stability as well as interesting physical properties, including a direct band gap, a high absorption coef cient, and p-type conductivity. These properties indicate CuO as an exciting semiconducting material to use an absorber layer in thin lms solar cells. For this speci c reason, this paper focuses on the synthesis of undoped and Ni-doped CuO thin lms by spray pyroly- sis process. Several techniques such as; X-ray diffraction (XRD), Raman spectroscopy, Scanning Electron Microscopy (SEM), Energy dispersive X-ray (EDX) and UV-Visible spectroscopy have been employed to characterize the synthesized samples. The XRD analysis indicated the formation of polycrystalline CuO thin lms and the average crystallite size was decreased from 35 to 20 nm for the samples with x = 0 to 8 at%, respectively. Furthermore, Raman spectroscopy also con rms the single-phase formation of CuO lms. The SEM images demonstrated that the incorporation of Ni in the CuO matrix improved the lms surface. The EDX analysis and the elemental mapping belay the homogeneous distribution of the elements. Moreover, UV-Visible spectroscopy has shown a signi cant expansion in optical energy band gap from 1.45 to 1.53 eV with an increase of Ni concentration. On the other hand, to investigate the impact of Ni-doped CuO on nanos- tructure Ni:CuO/ ZnO-NRs heterojunction solar cell performance, SCAPS-1D software is used. It has been found that, 8% Ni:CuO layer has been revealed as better for nanostructured solar cells. The results of this contribution will provide some vital guidelines for fabricating higher-ef ciency solar cells.

“…Copper oxide (CuO) is studied for its optical properties and applications as a p-type semiconductor, with a direct bandgap energy of 1.2 eV. CuO has been investigated for electronic, magnetic, and optical applications, since it can absorb light up to the near infrared region [1][2][3][4]. In addition, CuO nanostructures with various morphologies and sizes have been obtained by different methods of synthesis [5].…”

Copper oxide (CuO) films were deposited onto glass substrates by the microwave assisted chemical bath deposition method, and varying the pH of the solution. The pH range was varied from 11.0 to 13.5, and the effects on the film properties were studied. An analytical study of the precursor solution was proposed to describe and understand the chemical reaction mechanisms that take place in the chemical bath at certain pH to produce the CuO film. A series of experiments were performed by varying the parameters of the analytical model from which the CuO films were obtained. The crystalline structure of the CuO films was studied using X-ray diffraction, while the surface morphology, chemical composition, and optical band-gap energy were analyzed by scanning electron microscopy, X-ray photoelectron spectroscopy, and UV–Vis spectrophotometry, respectively. The CuO films obtained exhibited a monoclinic crystalline phase, nanostructured surface morphology, stoichiometric Cu/O ratio of 50/50 at%, and band-gap energy value of 1.2 eV.
