ROLE OF PHOTOSENSITIZER (ORANGE-G) IN PHOTOGALVANIC CELL FOR GENERATION OF SOLAR ENERGY

The Orange-G is used as photo sensitizer with EDTA as reductant for the enhancement of the conversion efficiency and storage capacity of photo galvanic cell for its commercial viability. The observed value of the photo generation of photo potential was 932.0mV and photocurrent was 265.0 ?A. The observed power at power point was 156.40 mW and the conversion efficiency was 1.50 %. The fill factor 0.5035 was observed experimentally observed at the power of the cell. The photo galvanic cell that developed can work for 140 min in dark. The storage capacity of the cell is 60.8%. The effect of different parameters on electrical output of the cell was observed. A mechanism has also been proposed for the generation of the photocurrent and photo potential in photo galvanic cell.
