Fabrication of a Photodetector Using Zinc Oxide Nanoparticles (Zno Nps) Prepared by Plant Synthesis

Abstract

The performance of the (ZnO/PSi) photo detector was improved by preparing zinc oxide nanoparticles (ZnO NPs) as colloidal nanoparticles utilising plant synthesis. These ZnO NPs were then coated using the drop casting method on p-type porous silicon (PSi) substrates as well as glass substrates to make thin films. The structural and morphological properties for zinc oxide nanostructure (ZnO NPs) deposited on glass substrate have been studied by using X-ray diffraction (XRD) and Atomic Force Microscope (AFM) and ultraviolet-visible radiation(UV-VIS) were carried out to find out the properties of nanoparticles and then zinc oxide nanoparticles were deposited on porous silicon wafers of the P-type using drop casting technique to create a Photodetector and then study its properties. The photovoltaic properties of the ZnO NPs/ Psi/ Si/Ag Photodetector have been published, as have the quantum efficiencies of the device.
