The effect of metal Ag nanoparticles on CdS/ZnTe heterojunction solar cells

Recent research on organic and inorganic solar cells has demonstrated that adding metal nanoparticles to the active layer can dramatically boost the performance of thin-film cells. In this research, Silver (Ag) nanoparticles have been added in CdS/ZnTe thin films that were prepared using the pulsed laser deposition (PLD) technique with laser energy ranging from (200-300 mJ). X-ray diffraction (XRD) analysis was used to examine the thin films of CdS and ZnTe for structural details. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) were also employed to examine the morphology of the films. The typical rectifier behavior was seen using the current-voltage (I-V) characteristic curves. Furthermore, by studying the effect of adding silver (Ag) nanoparticles on the capacitance-voltage (C-V) characteristics.
