Abstract

The spray pyrolysis technique has been employed to prepare uniform, large-area thin-film coatings of PbS on glass and on fluorine-doped tin oxide (FTO) conducting substrates at various substrate temperatures. Growth of polycrystalline PbS films occurred at a lower temperature (T-S = 275 degrees C) on conducting substrate than on glass (T-S = 325 degrees C) and oriented growth of polycrystalline cubic PbS occurred on FTO substrates. Characterization of the films has been carried out using x-ray diffraction, scanning electron microscopy and electrical resistivity studies. The optical transmittance spectra of these films have been taken for a wavelength range of 400-2500 nm. The films are found to be n type and their conductivities are of the order of 10(-4) (Omega cm)(-1). The lattice parameter value is presented. The average crystallite size of the films is of the order of 10(3) Angstrom and the average grain size is of the order of 10(4) Angstrom. Solar control properties of spray pyrolytically deposited PbS thin films have been investigated.
