The Effect of Different Remazol Dye Concentrations and Soaking Times in Dye-Sensitized Solar Cell

Water based Remazol Brilliant Red, Orange and Violet dyes were used as the dye sensitizer in dye-sensitized solar cell. The performance of the solar cell was investigated between the dye concentrations, 0.25 mM and 2.5 mM and three different soaking times which at 3 hours, 12 hours and 24 hours. The adsorption peaks of the dyes were observed using ultraviolet-visible-near infrared (UV-Vis-NIR) Spectrometer and the performance of the dye-sensitized solar cell was measured using Spectrum Parameter Analyzer (SPA). The results show that the device efficiency was increased with dye concentration, but, the DSSC performance at different soaking times performed differently with the previous study. The highest conversion efficiency of 1.125 % was obtained for Remazol Brilliant Red at concentration of 2.5 mM at 3 hours soaking time.
