Studies of surfactants in photogalvanic cells – NaLS-EDTA and azur-B system

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 814,0 mV and 255,0mA respectively. The observed conversion efficiency was 1,2% and the maximum power of cell was 207,57 mW. The storage capacity of the cell was 26,0 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.
