Photogalvanic solar energy conversion: Study with photosensitizers Toluidine Blue and Malachite Green in presence of NaLS

The photogalvanic effect of photosensitizer – reductant pair, Toluidine Blue–Arabinose and Malachite Green–Arabinose have been studied in presence of anionic surfactant NaLS (sodium lauryl sulphate) and a tentative mechanism has been proposed for the cell reaction. The photopotential (ΔV) and photocurrent (isc) were obtained 813.0 mV and 60.0 μA in Toluidine Blue system and 348.0 mV and 36.0 μA in Malachite Green system. The conversion efficiency and storage capacity of the developed cells were found to be 0.1448% and 123.0 min, respectively with Toluidine Blue system and 0.0590% and 32.0 min, respectively with Malachite Green system.
