Abstract
The photogalvanic effect was studied in photogalvanic cell containing nitrilotriacetic acid (NTA) as a reductant, Azur B as a photosensitizer and sodium lauryl sulphate (anionic), cetyl pyridinium chloride (cationic) and Tween 80 (nonionic) as surfactant from solar energy conversion and storage point of view. The conversion efficiency for anionic, cationic and nonionic surfactants above their cmc were 0.4053, 0.1386 and 0.2177% and storage capacity 105, 31 and 74 min respectively. The effect of variations of various parameters on electrical output and i-V characteristics of the cell were observed and a mechanism for generation of photocurrent has also been proposed.
