Abstract
Pomegranate dye has been used as green energy material in the fabrication of Dye sensitized solar cells (DSSCs) using nanocrystalline TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . Platinum was used as counter electrode. UV-vis, photoluminescence and FTIR studies of the dye as well as UV-vis on dye sensitized TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> films were carried out. Photovoltaic parameters like short circuit current (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SC</sub> ), open circuit voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OC</sub> ) 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 <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SC</sub> and V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OC</sub> was found to be 1.31mA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and 480 mV, respectively, which is quite high as compared to the earlier reported values on pomegranate dyes [1].
