采用Cu、SnS和ZnS三种靶材，采用共溅射技术制备了Cu2ZnSnS4（CZTS）薄膜太阳电池。通过在形成CZTS层之后将涂覆Mo的钠钙玻璃衬底上的CZTS层浸泡在去离子水（DIW）中，首次获得了超过6.7%效率的基于CZTS的薄膜太阳能电池。通过电子探针X射线显微分析发现，DIW浸泡具有优先刻蚀的效果，其选择性地消除CZTS层中的金属氧化物颗粒。(C)2008年日本应用物理学会。
Cu2ZnSnS4 (CZTS) thin film solar cells have been fabricated by co-sputtering technique using three targets of Cu, SnS, and ZnS. CZTS-based thin film solar cells over 6.7% efficiency were obtained for the first time by soaking the CZTS layer on the Mo coated soda-lime glass substrate in deionized water (DIW) after forming the CZTS layer. It was found that DIW-soaking had the effect of preferential etching, which eliminated selectively metal oxide particles in the CZTS layer, by electron probe X-ray micro analysis.
