The fabrication and measurement of natural dyes-based Dye sensitized solar cells (DSSCs) have been reported using low-cost solution-processable techniques. Titanium dioxide (TiO2) nanoparticles have been synthesized by a solvothermal process using Titanium isopropoxide (TIP) as a precursor. Two different natural dyes, Henna (Lawsonia inermis) and Indian blackberry (IBB; Syzgium cumini), and their cocktail were used as natural sensitizers with anatase-based nanostructure of TiO2 thin film on conducting glass substrate. Scanning electron microscopy (SEM) analysis reveals the uniform distribution of the crystalline anatase phase of TiO2 upon annealing at 550 ˚C. UV-Vis-NIR spectroscopy and SEM results divulge the absorption capability of dyes and the effect of dye loading on TiO2 photo-anodes, respectively. Electrochemical impedance spectroscopy (EIS) studies were carried to study the charge transport processes and its effect on the performance of DSSCs. These measurements show the least values of Rpt/Rct and Rpt for D3 dye sensitized DSSC as compare to the other two, with reduced rate of charge recombination resulting from the synergetic effect of co-sensitization of D1 and D2.  Thus, the cocktail dye showed promising photovoltaic performance due to an increase in absorption and better dye loading in the device.
