The paper presents a scope of different studies performed on thin-film mate
rials, commonly used as window layers in polycrystalline thin-film solar ce
lls. and prepared by the chemical bath deposition (CBD) method. The present
ed studies try to offer an approach to some key points of the chemical prep
aration that are directly related to the Anal quality and properties of the
films. Results on cadmium sulphide (CdS), cadmium sulphide-transparent con
ductive oxides interfaces (CdS/TCO (ZnO and ITO)), zinc selenide (ZnSe) and
indium hydroxy-sulphide In(OH)(x)S-y, are presented and discussed. (C) 200
