The photogalvanic effect studied in H-cell containing Ascorbic acid as reductant and Carmine as photosensitizer. The photopotential and photocurrent generated in cell were 884.0 mV and 190.0 μA, respectively. The observed conversion efficiency 0.8184% and the maximum output (power) of the cell was 85.12 μW. The photogalvanic cell can be used at this power level for 170 minutes. The effect of different parameters of electrical output of the cell was investigated and a cell photoreaction mechanism for the generation of the photocurrent in this photogalvanic cell has also been proposed.
