Abstract
Photogalvanic effect was studied in photogalvanic cell containing Glycerol as reductant and Congo red as photosensitizer. The photopotential and photocurrent generated were 587.0mV and 110.0mA respectively. The power of the cell was 45.0mW at its power point. The observed conversion efficiency was 0.66% and fill factor was determined as 0.74. The photogalvanic cell can be used in dark for 40 min. showing the storage capacity of the cell against charging time was 180 min. The effects of different parameters on electrical output of the cell were observed.
Keywords: Photogalvanic cell, photosensitizer, cell efficiency, Congo red.
