MICELLIZATION OF MIX DYE, CELESTINE AND METHYLENE BLUE-EDTASODIUM LAURYL SULPHATE SYSTEM FOR THE GENERATION OF ELECTRICITY IN A PHOTOGALVANIC CEL

ABSTRACTCelestine and Methylene blue has been used as a photosensitized in photogalvanic cell for solar energyconversion. EDTA was used as an electronic donor (reductant) and sodium lauryl sulphate (surfactant) wasused as an anionic micelle for greater photoejection of electrons. The photopotential and photocurrentwithout surfactant was found to be 692 mV and 71 mV respectively whereas with surfactant their valueswere found to be 744 mV and 104 μA respectively. The effect of various parameters on the electrical outputof the cell has been studied. The current voltage (i-V) characteristics of the cell have also been observed.Performance of the cell was determined in dark at its power point.
