Abstract
Fluoroscein has been used as a photosensitizer in photogalvanic cell for solar energy conversion. EDTA was used as an electron donor. The photopotential and photocurrent generated by this cell were 418 mV and 42 μA, respectively. The effect of various parameters like pH, light intensity, diffusion length, reductant concentration, dye concentration, etc. on the electrical output of the cell has been studied. The current voltage (i–V) characteristics of the cell has also been observed and a tentative mechanism for the generation of photocurrent has been proposed. Performance of the cell was determined in dark at its power point.
