Abstract: Photogalvanic effect was studied in photogalvanic cells containing EDTA as reductant, new methylene blue, and safranine O as photosensitizer. The photopotential and photocurrent generated were 740 mV and 110 μA, respectively. The observed conversion efficiency was 0.4442% and the maximum output (power) of cell was 81.4 μW. The photogalvanic cell can be used for 95 min in the dark due to the storage capacity of the cell. The effects of various parameters on the electrical output of the cell were observed. The mechanism of generation of the photocurrent in these photogalvanic cells has also been proposed. [ABSTRACT FROM AUTHOR]
