Abstract

Photogalvanic effects was studied in photogalvanic cell containing ascorbic acid as reductant and eiosin as photosensitizer. The photopotential and photocurrent generated were 860.0 mV and 90.0 μA, respectively. The observed conversion efficiency was 0.4474% and the maximum power of cell was 46.5 μW. The storage capacity of the cell as 36.0 min in dark. The effect of different parameters on electrical output of the cell was observed and a mechanism has also been proposed for the generation of photocurrent in photogalvanic cells.
