Electrodeposition and Characterization of Very Thin Film II-VI Compounds for Novel Superlattice Solar Cells Available to Purchase

Thin films of lead telluride (PbTe) and zinc telluride (ZnTe) have been electrodeposited on indium tin oxide (ITO)-coated glass substrates. Uniform dense films of ∼ 100 nm have been obtained for both materials. The electrochemical deposition procedures for fabricating these films are described. The as-deposited films have been characterized by scanning electron microscopy, energy dispersive spectroscopy, and optical absorption spectrophotometry. Multi layer structures, up to 3 layers, of ZnTe/PbTe films, have been fabricated.
