Abstract

Pomegranate dye has been used as green energy material in the fabrication of Dye sensitized solar cells (DSSCs) using nanocrystalline TiO₂. Platinum was used as counter electrode. UV-vis, photoluminescence and FTIR studies of the dye as well as UV-vis on dye sensitized TiO₂ films were carried out. Photovoltaic parameters like short circuit current (I_SC), open circuit voltage (V_OC) and fill factor (FF) were evaluated for fabricated cells. The maximum efficiency for the cell was found to be 1.1%. The maximum value of J_SC and V_OC was found to be 1.31mA/cm² and 480 mV, respectively, which is quite high as compared to the earlier reported values on pomegranate dyes [1].
