| dc.description.abstract | This research explores the green synthesis of zinc oxide nanoparticles using Carica papaya leaf extract as a reducing agent. With a focus on developing reliable, eco-friendly, and cost-effective nanomaterial for device technologies, this sustainable method offers an alternative to conventional bulk material synthesis. Synthesized powder samples were characterized using XRD, FTIR, UV-Vis spectroscopy, SEM, EDX, and TEM. Spin-coating technique was used for thin-film deposition, while current-voltage properties were measured using a four-point probe system connected to a Keithley 2400 measurement unit and a solar simulator. Absorption peaks ranged from 299-382 nm as recorded from UV-visible, which is inferior to bulk material at 410 nm. The band gap energy was estimated to be 3.47 eV, resistance 5192.63 Ω, resistivity 132.0038 Ωm⁻¹, and conductivity 7.6×10⁻³ Sm⁻¹ were determined. These results highlight ZnO nanoparticles potential for renewable energy and semiconductor applications | |
