This work presents results concerning the preparation and study of the optical and electrical prop-erties of SnS thin films. This is a new material, which exhibits excellent properties to be used as absorbent layer in solar cells. The SnS films were grown through a process, including a chemical reaction of the precursor species, and co-evaporated on a previously heated substrate. The effect of the deposition parameters on the spectral transmittance, resistivity and conductivity type was studied. Finally, the energy band gap Eg and absorption coefficient was determined from the transmittance measurements.
Key Words: SnS thin films, Co-evaporation.
