Abstract: This article focuses on the importance of Dye Sensitized Solar Cells (DSSCs) which use the combination of ZnO and ZnO/TiO2 based semiconducting materials that capture a large range of photon energies in the solar spectrum. The nanoparticles ZnO/TiO2 were prepared by using simple chemical precipitation method. The materials were characterizations using powder X-ray diffraction (XRD), UV–Vis absorption spectra and Field emission Scanning electron microscope (FE - SEM) with Energy dispersive analysis of X-ray (EDAX). The efficiency of the material was calculated in order to know its suitability for the fabrication of DSSCs. The results confirm that the combination of ZnO with TiO2 nanomaterials show higher conversion efficiency with naturally extracted Anthroquinones dyes. This material combination is a highly promising agent for the enhancement of the conversion efficiency for the fabrication of high efficient, low cost and high stable DSSCs.
