Fabrication of solar cells using ZnO/MnO2/CdS nanocomposite as a catalyst

Abstract

The nanomaterials prepared in the study were used by hydrothermal chemical method to generate dye sensitized cells (DSSCs) and were also used as photoelectrodes using two natural dyes as absorbent media: red (Hibiscus sabdariffa) and green (Apium Gravolens). The ternary nanocomposite (ZnO/MnO2/CdS) was prepared. The results also showed that the green dye efficiency in DSSCs is greater than the red dye in terms of conversion efficiency (η), and the ternary nanocomposite was also characterized by (SEM, TEM, XRD, and AFM).
