摘要：

In this study, a buffer layer formed using the sputtering of ZnO followed by sulfurization is investigated to install into the Cu2ZnSnS4 (CZTS) solar cells. A buffer layer connects a light absorption layer and a window layer and it works as a separator of carriers. Therefore, its influence on solar cell performance is very severe. We aim to realize the simple full dry process for the production of CZTS solar cells without a wet process. CZTS is formed by RF sputtering using a Cu-Zn-Sn-S sintered target followed by sulfurization using H2S/N2 gases. The sulfurized ZnO buffer layer is formed by RF sputtering and following sulfurization using H2S/N2 gases. An Al-doped ZnO layer as a window layer is applied to the solar cells. In this report, the optical and structural characteristics of sulfurized ZnO and its influence on solar cell performance are investigated.
