The photo galvanic cells were determined the photo potential, photocurrent, conversion efficiency, power of cell and performance of cell .The effects of various parameters like pH, light intensity, diffusion length, reductant concentration and dye concentration on the electrical output of the cell is studied. The current voltage (i–V) characteristic of the cell is also studied and a mechanism for the generation of photocurrent is proposed. Copyright@ International Science Community Association
