<b>Investigation of Surface Morphology and Electrical Properties of Ti-Doped ZnO Thin Films Using Digitally Controlled Chemical Spray Pyrolysis Technique</b>

Abstract

This study presents an investigation of the morphology and electrical properties of ZnO as well as Ti-doped ZnO thin films, utilizing a fabricated digital spray pyrolysis device at 350°C. It aims to evaluate the influence of titanium (Ti) doping on the morphology and electrical properties of ZnO thin films in order to assess their suitability for solar photovoltaic applications. Thin films of both ZnO and Ti-ZnO were prepared from extremely pure zinc acetate (Zn (CH3COO)2.2H2O) as well as titanium dioxide (TiO2) precursors. According to scanning electron microscope micrographs, the findings of both the undoped and doped films were seen to be evenly distributed across the substrates. The energy dispersive X-ray results indicated that Zn, O, and Ti were present in the films' elemental composition. The films I-V characteristics demonstrated an improvement of current as the doping increases, with 6% Ti-doped ZnO having the highest conductivity at . Thin films of ZnO doped with Ti produced in this investigation have morphological and I-V properties that suggests possible applicability in photovoltaic systems
