Copper indium gallium selenide (CIGS) thin film solar cells have been regarded as a candidate for energy conversion devices owing to their high absorption coefficient, high temperature stability, and low cost. ZnO:Al thin film is commonly used in CIGS solar cells as a window layer. In this study, ZnO:Al films were deposited on glass under various post-heat temperature using RF sputtering to observe the characteristics of ZnO:Al films such as Hall mobility, carrier concentration, and resistivity; subsequently, the ZnO:Al films were applied to a CIGS solar cell as a window. CIGS solar cells fabricated with various ZnO:Al films were analyzed in order to investigate their influence. The test results showed that the improvement of ZnO:Al characteristics affects Jsc and Voc in the solar cell through reduced recombination and increase of optical property.
铜铟镓硒（CIGS）薄膜太阳能电池因其高吸收系数、高温稳定性和低成本，被视为能量转换装置的候选者。ZnO:Al薄膜通常作为窗口层用于CIGS太阳能电池。在本研究中，使用射频溅射在不同的后热处理温度下在玻璃上沉积ZnO:Al薄膜，以观察ZnO:Al薄膜的特性，如霍尔迁移率、载流子浓度和电阻率；随后，将ZnO:Al薄膜作为窗口应用于CIGS太阳能电池。对用不同ZnO:Al薄膜制备的CIGS太阳能电池进行分析，以研究其影响。测试结果表明，ZnO:Al特性的改善通过减少复合和提高光学性能来影响太阳能电池的短路电流密度（Jsc）和开路电压（Voc）。
