Role of Rose Bengal-Oxalic Acid System for Generation of Electrical Energy in Photo Galvanic Cell
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2013, Vol 3, Issue 1
Abstract
Rose Bengal is used as a photo sensitizer in photo galvanic cell for solar energy conversion and Oxalic Acid is used as an electron donor in this study. The effects of various parameters like pH, light intensity, diffusion length, reductant concentration and dye concentration on the electrical output of the cell is studied. The photo potential and photocurrent generated by this cell are 870 mV and 120μA, respectively. The current voltage (i–V) characteristic of the cell is also studied and a mechanism for the generation of photocurrent is proposed
