A cleaner approach towards deposition of CdS thin films by an electrochemical technique
Abstract
CdS thin films have been deposited on Transparent Conducting Oxide (TCO, containing SnO2: F) coated glass substrates from aqueous sodium thiosulfate solutions, using the galvanic technique. A cadmium foil was used as a sacrificial anode and was the only source of Cd++ ions for CdS thin films, no external bias being used during film depositions. The films have been characterized using X-ray diffraction, SEM, EDX, AFM and optical absorption studies. AAS analyses were carried out to determine the Cd content in solutions after film deposition.
