  • 本論文中,是使用本實驗室的DC sputter & RF sputter 機台以及中山大學曾百亨教授實驗室的RTA Selenization,以及本實驗室的RF sputter來完成整個CIAS solar cell 元件。
    首先以soda lime glass 作為基板,先以DC sputter鍍上Mo金屬作為back contacts,之後再鍍上Cu、In、Al作為CIAS材料的source;不同於一般co-sputter的作法,我們再鍍Cu、In、Al時並沒有同時參入硒,而是之後再使用硒粉升溫來參入硒,硒化時使用快速硒化法和慢速硒化兩種方法,之後使用化學浴沉積法來鍍製buffer layer,我們選擇以ZnSe來作為我們元件buffer layer的材料,最後以RF sputter鍍上ZnO以及ITO最厚鍍上鋁柵型電極作為上電極。
