A photogalvanic cell containing Azur C as the photosensitizer and EDTA as the reductant has been investigated for solar energy conversion. The photopotential and photocurrent generated by this cell were 879 mV and 75 μA, respectively. The effects of various parameters on the electrical output of the cell have been studied. The current/voltage ( i/V ) characteristics of the cell have also been observed, and a tentative mechanism for the generation of the photocurrent in the photogalvanic cell has been proposed. The performance of the cell was determined in darkness at its power point.
