Use of fuchsine basic: Ethylenediaminetetraacetic acid system in photogalvanic cell for solar energy conversion

Abstract Fuchsine basic has been used as a photosensitizer in photogalvanic cell for solar energy conversion. Ethylenedianinetetraacetic acid was used as an electron donor. The photopotential and photocurrent generated by this cell were 650.0 mV and 60.0 μA, respectively. The effects of various parameters, such as 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 have 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.
