Abstract:
The present work deals with the study of ZnS thin film synthesis by chemical bath deposition
technique (CBD). The latter is known to be cheap and simple which motivates our choice of
this method. We have used Zinc sulfate (ZnSO4), Thiourea (CS(NH2)2), ammonia (NH3) and
hydrazine (N2H4). thin films were prepared with two different parameters such as the pH
and the solution temperature. The structural, optical and electrical properties of the obtained
films were characterized by means of several techniques. From structural studies of ZnS films
we inferred that ZnS films have a cubic structure with a preferential orientation (111).
The optical studies reveal that ZnS films have a large transparency in the visible range. This
comforts their using as buffer layer in thin films solar cells.
