A new photosensitizer having two rhodanine acetic acid groups at meso-positions of a zinc porphyrin [meso-Rhod-Zn-Rhod] has been synthesized and characterized by UV-Visible, 1H NMR, MALDI-MS, fluorescence spectroscopies and cyclic voltammetry. The new photosensitizer was tested in dye-sensitized solar cells with three different liquid redox electrolytes and compared its efficiency (𝜂) with dyad. Both dyad and triad were also tested in DSSC using a polymer gel redox electrolyte and observed low efficiency because of small short circuiting current i.e. ISc though the IPCE is significantly high. The probable reason for the low efficiency small ISc has been attributed to the internal resistance of the cell.
