ABSTRACT The photogalvanic (PG) cells including the Fast Green FCF dye sensitiser with Fructose-reductant-based PG cells have been extensively studied at low intensity artificial sunlight. These cells have to show very high electrical output that too at natural sun intensity for being practically significant and applicable in daily life. Therefore, the present study of PGs of Fast Green FCF–Fructose with an efficiency enhancer chemical like sodium lauryl sulphate surfactant in an alkaline medium has been done to see their workable feasibility in natural sunlight with an investigation of optimal fabrication parameters. The cell has been found workable in natural sunlight with a greatly enhanced optimum cell performance compared to that for reported similar cells. The optimum cell performance in terms of maximum power, short-circuit current, open-circuit potential, efficiency and storage capacity (as half change time) is of the order of 649.6 µW, 2250 µ|A, 1048 mV, 8.12% and 59 min, respectively.
