| Abstract | Published 01/10/2019 Nanoparticles of semiconductor material have got more interest due to their desirable properties and applications in different areas. In this study Zinc Oxide Nanoparticles (ZnO NPs) were synthesized using laser ablation in water by applying (1600 pulses) of NdYAG laser (λ = 1064 nm) . The crystal structure and morphology of the synthesized ZnO NPs were investigated using X-Ray diffraction, atomic force microscope (AFM), optical microscope image, and optical properties characterized using UV-Visas well as FTIR spectroscopy. The investigation revealed high purity of the ZnO NPs thin film prepared with a regular and homogeneous semispherical shape nanoparticles distributed on the substrate surface with size around 50nm. The optical properties show energy band gap of (1.5 eV and 4eV) respectively. I-V characteristics have been studied for the heterojunction structure of (Ag/ZnO/Si/Al) indicates that this heterojunction could be used as a solar cell with efficiency about 10.9%. |
