Abstract
Copper tin sulfide Cu-Sn-S compounds have been grown by the spray pyrolysis technique at 360 °C using SnCl2·2H2O, CuCl2 and thiourea (SC(NH2)2 as precursors. Structural, morphological, and optical properties were studied showing that the obtained films crystallized in tetragonal and orthorhombic structures in terms of the Cu/Sn concentration ratio in the starting solution. Moreover, the deposited films showed a relatively high optical absorption coefficient of around 104 cm−1 and exhibited indirect transition gaps which lie within 1.17-1.38 eV domain.
