Abstract:
A type of semiconductor heterojunctions was
fabricated by ZnO thin film layer deposited on Si substrate.
The elementary particles were examined by Energy Dispersive
X-rays (EDX). X-ray Diffraction (XRD) analysis was
described by structural properties of ZnO and Si layer. The
study of ZnO growth morphology on Si substrate was
determined by Scanning Electron Microscope (SEM). Then,
the electrical and optical characteristics for ZnO-Si solar cell
was investigated. Thermally simulated current (TSC) and I-V
characteristics under different wavelengths in visible regions
were also studied. In this work, the ZnO-Si thin film layer was
indicated in photovoltaic effect. Moreover, studying silver
contact on ZnO-Si heterojunction was purposed for achieving
higher efficiency.
