| Abstract: | The photogalvanic effect, studied in a photogalvanic cell
containing cetyltrimethylammonium bromide as surfactant,
Rhodamine 6G as photosensitizer and oxalic acid as reductant, is
reported. The effects of concentrations of surfactant
photosensitizer and reductant, pH, diffusion length, electrode area
and temperature on electrical output of the cell are reported. The
observed photopotential and photoculTent are 414.0 mV and 90.0
μA, respectively. The observed conversion efficiency is 0.55 %,
fill factor is 0.45 and the maximum power output of cell is 25.22
μW. The photogalvanie cell can be used for 96 minutes in the
dark (the storage capacity of cell in dark). A mechanism has also
been proposed for the generation of photoeurrent in photogalvanic
cell. Dye-surfactant spectra have also been studied. |
