Abstract

Photogalvanic effect was studied in a photogalvanic cell containing Brilliant Black PN as photosensitizer in Ammonium Lauryl Sulphate-EDTA system. A sintered filter was used in H-cell between the diffusion length. In Brilliant Black PN- Ammonium Lauryl Sulphate-EDTA system the photopotential and photocurrent were observed 972.0 mV and 1125.0 μA respectively. The conversion efficiency of the system was observed 3.0490% and fill factor was determined as 0.25. The cell performance (storage capacity) was observed 130.0 minutes in dark. 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 studied. The mechanism was proposed for the generation of photocurrent in photogalvanic cell.
