Photogalvanic (PG) cell are dye-sensitized solution-based solar energy converters and storage devices. The photogalvanic of Bismarck Brown (BB) as a dye sensitizer with different reductant such as Ascorbic Acid (AA), EDTA, and Glucose (Glu.) have been investigated in order to obtain new insights into how to make PG cells that become relatively cheaper, cleaner, and environmentally acceptable. In this study, three systems BB - AA, BB - EDTA, and BB – Glu were examined utilizing PG cells. The Photocurrent generated by these systems was 915 mV, 810 mV and 720 mV and Photopotential generated by three systems was 155 μA, 135 μA and 120 μA, respectively. The factor of fill for BB - AA, BB - EDTA, and BB - Glu systems were 0.54 %, 0.48 % and 0.40 %, Efficiencies of conversion for BB - AA BB - EDTA, and BB - Glu systems were 0.899 %, 0.614 % and 0.405 % and Capacities of storage for BB - AA, BB - EDTA, and BB - Glu systems were 40 min., 34 min. and 31 min., respectively. The effects of various factors on the electrical outputs of the cell have been observed, and a mechanism for the generation of photocurrent in PG cells has also been suggested.
