Abstract

This article reported the effect of metal doping into natural dye on the performance of photosensitizer and DSSC efficiency. Natural dye was extracted from spinach leaves and nickel (II) chloride used as metal. The concentration of metal were varied of 0.01 M, 0.05 M, and 0.5 M. The absorbance of dye solutions and the dye adsorption on the TiO2 electrodes were characterized by UV-Vis spectroscopy. The electrical characteristic of dye solutions and DSSCs were measured using I-V meter. As a result, the absorbance of dye solutions increased in the wavelength above 700 nm. This region was light absorption of Ni metal. Increasing the concentration of Ni into chlorophyll dye also increased the value of conductivity. The optimum efficiency of DSSC was obtained at a concentration of 0.05 M, with the efficiency value was 0.0769%. This result was also supported by the highest absorbance of dye adsorption on the TiO2 electrode at a concentration of 0.05 M. The efficiency of DSSC increased up to 135% as compared to pure chlorophyll dye.
