In this research, the effect of the control condition on the physical properties of Copper Oxide (CuO) thin-film has been successfully performed through the sol-gel procedure followed by spin coating technique on a glass substrate. Taguchi model was reported to find the most prominent factor on the deposits process of CuO thin coat with an L9 (3³) orthogonal array. Besides, from XRD, we deduce the texture coefficient used to determine the S/N ratio. The selected influential parameters are: concentration of Copper (II) ions “Cu²⁺“, preheating temperature T_P and the final heat-treatment temperature T_f. The results showed that the obtained crystals exhibit a uniform and smooth morphology. The energy-dispersive X-ray spectroscopy (EDS) exploits the chemical composition of the prepared films. In addition, the Absorption spectra by UV–vis analysis of the obtained thin films reveal high absorbance in the visible range. In fact, the CuO films showed optimal gap energy of 1.47 eV. However, the prepared thin CuO films by the optimization of the Taguchi model lead to the enhancement of the optical properties and suggested that CuO thin film could be one of the potential solar cell absorbers in PV devices.

在这项研究中，控制条件对氧化铜 (CuO) 薄膜物理性能的影响已通过溶胶-凝胶程序和玻璃基板上的旋涂技术成功地进行。据报道，田口模型在具有 L9 (3 ³ ) 正交阵列的 CuO 薄涂层的沉积过程中找到了最突出的因素。此外，从 XRD 中，我们推导出用于确定 S/N 比的织构系数。选定的影响参数是：铜（II）离子“ Cu ²⁺ ”的浓度、预热温度T _P和最终热处理温度T _f. 结果表明，所得晶体具有均匀、光滑的形貌。能量色散 X 射线光谱 (EDS) 利用所制备薄膜的化学成分。此外，所得薄膜的紫外-可见分析吸收光谱显示在可见光范围内具有高吸光度。事实上，CuO 薄膜显示出 1.47 eV 的最佳间隙能。然而，通过优化田口模型制备的薄 CuO 薄膜导致光学性能的增强，并表明 CuO 薄膜可能是光伏器件中潜在的太阳能电池吸收剂之一。
