Abstract:
Photogalvanic effect was studied in photogalvanic cell
containing Ascorbic Acid as reductant and Victoria Blue as
photosensitizer. The photopotential and photocurrent generated
were 895.0 mV and 204.0 mA, respectively. The observed
conversion efficiency was 0.9254% and the maximum power of cell
was 94.6 mW. The storage capacity of the cell was 64 minutes in
dark. The effects of different parameters on electrical output
of the cell were observed and a mechanism has been proposed for
the generation of photocurrent in photogalvanic cell.
Keywords: Victoria Blue, Ascorbic Acid, Fill Factor, Conversion
Efficiency, Power Point, Storage Capacity.
