文摘

Photogalvanic cells are electrochemical devices capable of solar power generation and storage using solution of photosensitizer(s) and reductant(s) in alkali medium. These cells are cheap, renewable, and promising energy devices for the future, provided there electrical performance is further improved. The present study of photogalvanics of Naphthol Green B dye photosensitizer with Fructose as reductant and Sodium Lauryl Suphate as surfactant in alkaline medium was undertaken with aim of finding relatively better combination of chemicals like photosensitizer, reductant and surfactant for further improvement in electrical performance of these cells. This combination of chemicals has shown very impressive and surprisingly very high improvement in cell performance. The optimum conditions for cell have also been observed for optimal cell performance. The maximum power, short-circuit current, open-circuit potential, efficiency and storage capacity (as half change time) has been observed of the order of 422.4 μW, 1850 μA, 1040 mV, ?0.6%, and 260 min, respectively.
