The paper presents studies of optical and electrical properties of SnS1-xSex (x = 0.26-0.31) thin films deposited on glass substrates using thermal co-evaporation technique at different substrate temperatures, 200 degrees C-350 degrees C. The as-deposited films were characterized by the energy dispersive spectroscopy, X-ray diffractometry, scanning electron microscopy, optical transmission and reflection spectroscopy, four-probe resistivity and photoconductance measurements. The results have shown that deposited films can be used as absorber layers in thin film solar cell applications, and the optimal substrate temperature for the deposition is 300 degrees C.
