Abstract

In this work, we report the effects of the spin speed on the structural optical and electrical properties of CuO thin films deposited using spin coating technique at different speeds. The phase structure of the produced thin films shows a pure monoclinic structure, with (002) orientation as most intense. The films deposited at 3000 rpm have shown a high absorbance with an optical band gap about 1.83 eV. The electrical conductivity of the elaborated films increases with an increase in coating speed. Our results reveal that the CuO thin films have the potential to be developed in solar cell applications.

纺丝速度对溶胶-凝胶旋涂CuO薄膜物理性能的影响

摘要

在这项工作中，我们报告了旋转速度对使用旋涂技术以不同速度沉积的CuO薄膜的结构光学和电学性质的影响。所生产的薄膜的相结构显示出纯单斜晶结构，其中（002）取向最为强烈。以3000 rpm的速度沉积的薄膜显示出高吸收率，光学带隙约为1.83 eV。精加工薄膜的电导率随涂覆速度的增加而增加。我们的结果表明，CuO薄膜具有在太阳能电池应用中开发的潜力。
