The Sodium lauryl sulphate (NaLS) has been used as anionic micelle species; Safranine as photosensitizer and D-Xylose as electron donor for the enhancement of the electrical output and performance (storage capacity) of the photogalvanic cell with reduce the cost of construction for commercial viability. The photopotential and photocurrent generated were 893.0 mV and 207.0 µA; respectively. The observed conversion efficiency and the fill factor were 0.6800% and 0.3233; respectively at the power point of the cell. The photogalvanic cell can be used for 98.0 minutes in the dark.The effect of different parameters like concentration of micelles; photosensitizer and electron donor; variation of pH; light intensity and diffusion path length were observed. A current – voltage (i-V) characteristics of the photogalvanic cell was studied experimentally and a mechanism has also been proposed for the generation of the photocurrent. All observed results of the system were lower in absence of the micelles species.
