Production of Electricity and Improved Conversion Efficiency By Using Ionic Liquid in Photogalvanic Cell

Résumé

Abstract Surfactant were widely applied in photogalvanic cells (PGC), and a limited number of studies have reported to used ionic liquid (IL), although it has more advantages than the conventional surfactants due to their specific chemical and physical properties such as the high electrolytic properties, the strong hydrophobic interactions between Cnmim+ and hydrophobic portion of other surfactant and co-surfactant behavior. In this work, Synthesis of IL Diethyl ammonium tetrachloro ferrate (DATF) was done through two step method. The composition of the produced IL was investigated by FTIR and 1HNMR spectra techniques. IL was known as a salt in the liquid state or a salt with melting point below the boiling point of water. PGC can be described as an electrochemical cell, where the change in both voltage and current results from photochemically generated changes in the proportional concentrations of the reactants during the oxidation-reduction reaction in the cell. The present study has shown electrical cell performance of the PGC as PPP 96.2μW, iSC 370 μA, VOC 650 mV, η 1.9 %, and t0.5 105 minutes, for PGC system containing Tris (2,2'-bipyrdyl) Ruthenium (II) chloride hexahydrate (TBRC) as photosensitize, Oxalic acid (OX) as reductant and (DATF) as IL under artificial and low illumination intensities, this system not yet reported in the literature. The study of variation of the different cell parameters has shown optimum cell performance at an optimal value of these cell fabrication parameters, and a preliminary mechanism for the production of energy in PGC was also proposed.
