Studies of the Micellar Effect on Photogalvanics: Solar Energy Conversion and StorageEDTA-Safranine O-NaLS System
The studies of the micellar effect on photogalvanics were done for solar energy conversion and storage in photogalvanic cell containing sodium lauryl sulphate as anionic micellar species, ethylenediamine tetra acetic acid as reductant, and Safranine O as photosensitizer. The photopotential and photocurrent generated were 871.8 mV and 200.0 A, respectively. The observed conversion efficiency was 0.7213%, the fill factor was 0.35, and the maximum power of the cell was 174.2 W, whereas the power at the power point of the photogalvanic cell was 75.02 W. The rate of initial generation of current was 50.0 A min(1). The photogalvanic cell can be used for 40.0 min in the dark. The effects of different parameters on the electrical output of the photogalvanic cell were observed and a mechanism was proposed for the generation of photocurrent in the photogalvanic cell.
