Effects of Sulfurization Pressure on the Conversion Efficiency of Cosputtered Cu2ZnSnS4 Thin Film Solar Cells

Effects of Sulfurization Pressure on the Conversion Efficiency of Cosputtered Cu2ZnSnS4 Thin Film Solar Cells

We report herein Cu2ZnSnS4 (CZTS) thin film solar cells with 6.75% conversion efficiency, without an antireflection coating. The CZTS precursors have been prepared by cosputtering using three different targets on Mo-coated substrates: copper (Cu), tin sulfide (SnS), and zinc (Zn). The postsulfurizat...
