Chemical Bath Deposition of In2S3 Thin Films as Promising Material and Buffer Layer for Solar Cells

The copper(I) and indium thin films are obtained by chemical bath deposition (CBD). Their elemental composition and microstructure were particularly studied by means of the x-ray photoelectron spectroscopy (XPS). The change in the surface microstructure of thin films depending on the temperature and the composition of reaction bath were determined by means of scanning electron microscopy (SEM).
