Photogalavanic effect was studied in a photogalvanic cell containing NaLS, Ascorbic acid and Azur B as a surfactant, reductant and photosensitizer, respectively. The photopotential and photocurrent generated by this system were 971.0 mV and 185.0 μA respectively. The observed conversion efficiency was 0.9646% and fill factor was determined as 0.41. The cell performance was 135.0 min in dark. The effect of different parameters on the electrical output of the cell were observed, current-voltage characteristics of the cell have also been studied and mechanism has been proposed for the generation of photocurrent in photogalvanic cell.
