The main aim of the research work presented in this thesis was to synthesise nanostructured PbS absorber layer for solar cell devices using simple and economical methods: chemical bath deposition (CBD), microwave assisted chemical bath deposition (MACBD) and thermal evaporation (TE). The synthesis of nanostructured PbS layers using CBD was carried out by changing Pb2+ ions source, deposition time, and molar concentration. The results showed that the morphology and size-scale of nanostructured PbS features are highly dependent on each parameter. X-ray diffraction analysis (XRD) analysis revealed that all nanostructured PbS thin films exhibit a cubic rock salt (NaCl) type structure. The optimal condition to synthesise nanostructured PbS using CBD was lead nitrate as Pb2+ ions source with 0.1M molar concentration. The PbS sample with optimum conditions was selected to be used as an absorber layer on the PbS/CdS/ITO solar cell device.
