Abstract	In this work, we have fabricated Core-Shell Si/CdS nanowires heterojunction structures by preparing n type cadmium sulfite nanoparticles (CdS-NPs) on a large area of vertically alight p type of Si nanowires (Si-NWs). The CdS-NPs were fabricated by chemical bath deposition (CBD), while the Si wafer was etched in chemical solution to obtain Si-NWs. SEM images show 2-D CdS-NPs are well adhesive on Si-NWs. The Optical properties of different thicknesses CdS-NPs thin films fabricated on glass slide and on Si-NWs were studied by measuring their UV-Visible absorption and Raman spectra. The structure of CdS-NPs thin film was investigated by XRD. We deposited Al doped ZnO (AZO) film on CdS-NPs/Si-NWs heterojunction as electrode to improve the performance of the heterojunction devices. We have also studied the performance of the solar cell before and after depositing AZO, its dependence on the length of Si-NWs, and on the thickness of the CdS-NPs layers. The results of these studies are presented in this paper.
