Electrodeposition and characterization of very thin film II–VI compounds for novel superlattice solar cells

Thin films of lead telluride (PbTe) and zinc telluride (ZnTe) have been electrodeposited on indium tin oxide (ITO)-coated glass substrates. The electrochemical deposition procedures for fabricating these films are described. The as-deposited films have been characterized by scanning electron microscopy, electron dispersive spectroscopy, and optical absorption spectrometry. The results of this structural and optical characterization are presented in this paper.
