| Outline of Final Research Achievements |
In this study, we demonstrated formation of CZTS nano-cylinder arrays on Si nanowire arrays as a template to realize high performance photovoltaic cell using environmentally-friendly CZTS light absorber. The nano-cylinder shaped CZTS arrays indicated high light absorbance property and high photo-induced current compared with film CZTS sample. Additionally, we established sufurization condition for CZTS precursor using CS2 liquid which is reratively safe and easy-to-handle compared with conventional H2S and S powder surfer source. These results will provide the safe and environmentally friendly preparation method, and will realize high performance CZTS photovoltaic cells.
