Semiconducting materials have an application in solar cells in which thin films and nanocrystals might be employed. Ternary/quaternary alloying of semiconducting materials can enhance optical and structural properties. Cadmium sulfide films have low absorbance to the solar spectrum. Hence they have been widely used as a window material, or as a buffer layer in thin film photovoltaic cell technology and as transition metal-chalcogenide materials, which occur with many stoichiometries and many structures, e.g. cadmium sulfide, zinc sulfide, lead sulfide and with alloyed compounds. New routes to thin films of chalcogenide materials are reported in this thesis: zinc doped in cadmium and the alloying of cadmium into lead; all chalcogenides materials were successfully achieved by a spin coating (SC) method from single source precursors (SSPs). SC produced effective thin films at inexpensive cost that are suitable for integration into solar cells.
