alternatives is an urgent necessity in the field of solar cells. Due to their environmentally
friendly and optical properties, CZTS and CZTSe kesterite materials have been proposed as
promising alternative compounds in thin film solar cell applications. In this study, a numerical
investigation of a CZTS/CZTSe tandem solar cell structure is conducted using SILVACO
software. In this structure, CZTS and CZTSe serve as the main absorbers in the top and …
