Performance of Dye-Sensitized Solar Cell using Hamelia Patens leaves as natural dye

Abstract Dye-Sensitized Solar Cells (DSSC), a 3rd generation solar cell has gained huge attention in the field of photovoltaics as substitute for silicon cell. The performance DSSC mainly depends on all important components such transparent conductive oxide substrate, cathode, photo-anode, dye, and electrolyte. Additionally, sensitizing dyes also perform vital role absorption light conversion energy into electrical DSSC. However, its efficiency is low it consumes good amount manufacturing. In this respect scientists researcher are more focus how to improve efficacy production cost make economically viable. For purpose, present work we have natural from Hamelia patens plant’s leaf which available throughout year fabrication at temperature. Semiconductor film electrode, ZnO been synthesized via. chemical bath deposition process, anchored FTO glass substrate. Various characterizations techniques UV-vis absorption, FTIR were done extracted dye. XRD FE-SEM performed crystallinity morphological analysis material. data reveals formation hexagonal (JCPDS card no. 01-082-9744 where 2?° 31.799, 34.454, 36.289, 47.586 corresponds (100), (002), (011), (012) respectively). Using dyes, sandwiched type fabricated various parameter power efficiency, Voc (open circuit voltage), Isc (short current) measured continuous 3 days. DSSCs by using dye leaves (sample 1) shows = 132.2 .065 mA.
