Abstract

Different concentrations of Ni-doped anatase TiO2 nanoparticles were prepared by icebath co-precipitation method to examine the effects of various Ni2+ concentrations on the power exchange mechanism in photovoltaic performances of dye-sensitized solar cells (DSSC). X-ray powder diffraction (XRD) revealed a single anatase phase present in all samples together with three times reduction of particle size with the addition of Ni2+. Nanoparticle size exhibited better uniformity under scanning electron microscopy (SEM) with an increase of Ni2+ ions. Fourier Transform Infrared Spectroscopy (FTIR) confirmed the formation of Ti-O-Ni bonding due to sharpened and enhanced intensity of the bands in the range of 500-1000 cm-1 and 910-1030 cm-1. Ni2+ concentrations also increased both open-circuit voltage (Voc) and short-circuit current (Isc). The optimum concentration of Ni-doping obtained was at 0.075M of Ni which shows a maximum DSSC efficiency of 0.38%.
