Study of the Performance of a ZnO-NiO/Si Nanocomposite-Based Solar Cell

Abstract

In this work, we fabricated a novel (Zinc Oxide-Nickel Oxide) ZnO-NiO/Si (silicon) solar cells using ZnO-NiO thin films. We synthesized the nanocomposite films at different mixing concentrations and deposited them on silicon. We completed the fabrication of the solar cells by adding silver front and back contacts. The objective of this work is to increase power conversion efficiency for solar cells. We used I-V in the dark and under illumination as well as impedance spectroscopy to highlight the enhancement of the electrical and optoelectronic results. We found that the carriers lifetime reached 6.1 ms, and the series resistance Rs 0.017 Ω cm2 for the ZnO-NiO/Si solar cell. The power conversion efficiency reached 14%. The novel nanocomposite thin film improved solar cell conversion efficiency.
