Abstract
Photogalvanic cell containing Rose bengal as photosensitizer, D-Xylose as electron donor and dioctyl sodium sulphosuccinate (DSS) as micelles species, was used for conversion of solar energy into electric power through a H shape type solar cell of 25.0 ml volume only. The optimum performance in terms of photo potential, photocurrent, storage capacity and conversion efficiency was observed as 715.0 mV, 395.0µA, 55.0.0 min., and 0.95%, respectively in absence of micelles (DSS), whereas 910.0 mV, 590.0µA, 142.0 min., and 1.54%, respectively in presence of micelles. The micelles species dioctyl sodium sulfosuccinate (DSS) promote the separation of photoproducts via hydrophilic-hydrophobic interactions between the products, thus improving the efficiency and storage capacity of the photogalvanic cell. However, considerable challenges must be addressed before photogalvanic cells can be employed for both solar power generation and storage. Some challenges include dye photo degradation, platinum (Pt) corrosion, liquid evaporation, breaking the weakness of the SCE/combination electrode, and the necessity to enhance the conversion efficiency and storage capacity.
