제목 Improved device performance of Ge doped CZTSSe solar cell over 10% conversion efficiency
초록 Effect of germanium (Ge) doping on crystal growth and device properties of CZTSSe thin-film solar cells were investigated. CZTSSe thin films were prepared by stacked layers from Zn, Sn and Cu metal targets using sputtering followed by post sulfo-selenization process. It was observed that the doping of Ge improves the grain growth, compactness, and crystallinity of the CZTSSe absorber layer results enhanced solar cell device performance from 7.28 to 10.09%. These results suggest the possibility to achieve a further improvement in the optoelectronic characteristics of the solar cells that could be accomplished by optimization of processes with a fine-tuning of the Ge doping in the CZTSSe absorber material.
