      Photogalvanic effects were studied in photogalvanic cells containing sodium lauryl sulphate as surfactant, EDTA as reductant and azur-B as photosensitizer. The photopotential and photocurrent generated were 814#x00B7;0 mV and 255·0 μA respectively. The observed conversion efficiency was 1·2% and the maximum power of cell was 207·57 μW. The storage capacity of the cell was 26#x00B7;0 min in dark. The effect of different parameters on electrical output of the cell was observed. A mechanism has been proposed here for the generation of photocurrent in photogalvanic cells
