Studies of anionic surfactant on energy conversion and storage capacity in a photogalvanic cell containing Rhodamine 6G-EDTA-NaLS system. Photogalvanic cell is a device in which solar energy converts into electrical energy via formation of energy rich species that exhibit the photosgalvanic effect. The photopotential and photocurrent of the cell is observed 905.0 mV and 450.0 μA respectively. The conversion efficiency and fill factor of the cell are determined 1.26 % and 0.2516 respectively. The storage capacity (performance) of the cell is observed 170.0 minutes in dark. The effects of different parameters on the electrical output of the cell are observed and current-voltage (i -V) characteristics of the cell are also studied. The mechanism is proposed for the generation of photocurrent in photogalvanic cell.

Keywords: photogalvanic effect, photopotential, photocurrent, conversion efficiency, storage capacity.
