摘要：

This study reports the preparation of Cu2ZnSnS4 (CZTS) thin films by magnetron sputtering deposition with a Cu-Zn-Sn ternary alloy target and sequential sulfurization. The effects of substrate temperatures on the structural, morphological, compositional as well as optical and electrical properties were characterized. The results showed the CZTS thin films prepared by sulfurization at substrate temperature of 570 A degrees C yielded secondary phases along with CZTS compound. The relatively good properties of CZTS thin film were obtained after sulfurization at substrate temperature of 550 A degrees C. This CZTS film showed compact structure with large grain size of 900 nm, direct optical band gap of 1.47 eV, optical absorption coefficient over 10(4) cm(-1), resistivity of 4.05 Omega cm, carrier concentration of 8.22 x 10(18) cm(-3), and mobility of 43.38 cm(2) V-1 S-1.
