Abstract
The photovoltages and photocurrent in photogalvanic cell were studied for conversion and storage of solar energy by using yellow 5GN as a photo sensitizer and EDTA as a reductant. The observed cell performance in terms of photopotential, photocurrent, conversion efficiency, fill factor and storage capacity in terms of half change time are 905.0 mV, 450.0 μA, 1.45%, 0.5 and 170.0 minutes on irradiation for 140 minutes, respectively. The effects of different parameters on electrical output of the cell were observed and a mechanism has been proposed for generation of the photopotential and photocurrent in photo galvanic cell.
