Use of Trypan blue-Arabinose System in Photogalvanic Cell for Solar Energy Conversion and Storage

Photogalvanic effect was studied in the cell containing Trypan blue as photosensitizer in Arabinose-NaOH system. The conversion efficiency of the cell, fill factor and the cell performance were observed 0.80%, 0.23 and 140.0 minutes in dark respectively. The effects of different parameters on the electrical output of the cell were observed and current-voltage (i?V) characteristics of the cell were also studies. The photopotential and photocurrent were observed as 834 mV and 350 ?A respectively. The mechanism was proposed for the generation of photocurrent in photogalvanic cell.
