Abstract

In this paper, composite of TiO2/ZnO nanoparticles were synthesized as photoanode material in fabrication of dye-sensitized solar cell (DSSC) and characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) analyses and then synthesized nano-powder turned into a paste using prepared solution. It is demonstrated that this nano-composite photoanode provides better photovoltaic performance compare with using bare form of mentioned semiconductor oxides. The performance of fabricated cell was evaluated with solar simulator (100 mW/cm2) and photoelectric conversion efficiency (PEC) of 1.04% is given. Also, other photovoltaic parameters include short circuit current density (ISC), open circuit voltage and fill factor are 4.84 mA/cm2, 0.7045 V and 0.3047, respectively.
