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 (ISC), open circuit voltage (VOC) 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 JSC and VOC 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].
