Ponceau-S is used as a photo sensitizer in photogalvanic cell for solar energy
conversion and mannitol is used as an electron donor in this study. 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 photopotential and
photocurrent generated by this cell are 1080 mV and 240 μA, respectively. The current
voltage (i-V) characteristic of the cell is also studied and a mechanism for the generation of
photocurrent is proposed.
