Cadmium-sulphide/copper-sulphide thin-film solar cells: review of methods of producing the CdS and Cu2S layers

The methods that have been used successfully for the production of cadmium-sulphide layers in thin-film solar cells are described. The structural, optical and electrical properties of the resulting layers are discussed and related to the properties required in a high-efficiency thin-film solar cell. A description is also given of some less commonly used methods that might be developed into successful techniques for the production of large-area low-cost solar cells
