Efficient Solar Energy Conversion and Storage Through Photogalvanic Cell Based on EDTA: Brilliant Green and Fast Green System

Abstract

Quest for devising efficient and cost effective energy systems is on. Solar energy is an everlasting and omnipresent source of clean energy. Photogalvanic cells are a potent medium through which solar light may be harnessed gainfully. A mixed dye system Ethylene diamine tetra acetic acid (EDTA)-brilliant green and fast green has been used in place of a single dye system in the present work. Photopotential, photocurrent and other important operating parameters are recorded for photogalvanic cell based on mixed dye system. Experiments are performed with different concentrations of brilliant green and fast green with EDTA at different pH values to optimize the performance of the cell. Encouraging results have been obtained.
