The study aims to investigate the optical and structural properties of ZnO wurtzite heterostructure thin films in order to manufacture them as a new generation of solar cell transparent electrodes. With the Sol gel- spin coating process, the pure and co-doped Zinc oxide with different amounts of aluminum and silicon were prepared. The composition was realized in order to obtain thin films with Al + Si contents in the range of 0 at% to 6 at%. XRD patterns exhibit the ZnO wurtzite structure. XPS analysis sustain the presence of Al³⁺and Si³⁺ in Zn lattice sites. The optical investigations showed that the band gap varies between 3.23 eV and 3.28 eV, showing an increase with increasing the silicon amount. The studied thin films present a significant transmittance parameter in particular the with films having 2 at% of Si and 2% of Al with higher average value which reached 95%.

该研究旨在研究ZnO纤锌矿异质结构薄膜的光学和结构特性，以将其制造为新一代的太阳能电池透明电极。通过Sol凝胶旋涂工艺，制备了纯铝和共掺杂的铝和硅含量不同的氧化锌。实现组成是为了获得Al + Si含量在0at％至6at％范围内的薄膜。XRD图谱显示ZnO纤锌矿结构。XPS分析支持Al ³⁺和Si ³⁺的存在在锌晶格位。光学研究表明，带隙在3.23 eV和3.28 eV之间变化，表明随着硅含量的增加而增加。所研究的薄膜特别是具有2at％的Si和2％的Al的薄膜具有显着的透射率参数，具有更高的平均值，达到95％。
