The efforts have been made to convert solar energy into electrical energy by eosin as photosensitizer with different sugars fructose, arabinose, D-xylose, and mannose systems in photogalvanic cell along with providing them commercial viability using lower concentrations of the solutions. The generated photopotential and photocurrent are 848.0, 679.0, 825.0, and 758.0 mV and 240.0, 240.0, 250.0, and 170.0 μA, respectively. The maximum powers are 203.52, 162.96, 206.25, and 128.86 μW, respectively. The observed conversion efficiency is 0.8415, 0.6461 0.7026, and 0.6812% and the determined fill factors are 0.34, 0.37, 0.28, and 0.27 against the absolute value 1. The developed photogalvanic cell can work for 55.0, 75.0, 85.0, and 90.0 minutes in the dark. The photogeneration electricity is proved by a proposed mechanism. Conclusively, the photogalvanic cell so developed has shown appreciable conversion and storage of solar energy. Copyright © 2011 John Wiley & Sons, Ltd.
