Abstract
The conversion of solar energy on the basis of photogalvanic effect in liquid phase photogalvanic solar cell is studied experimentally. The photogalvanic effect has been studied in system containing Rhodamine B as a photosensitizer and DTPA as a reducing agent in presence of sodium lauryl sulphate. The photopotential and photocurrent generated by this system were 843.0 mV and 185.0 μA, respectively. The experimental conversion efficiency, fill factor, storage capacity of this cell have also been determined. The effect of different parameters on electrical output of the cell like effect of dye, reductant and surfactant concentration, pH, light intensity, temperature, diffusion length and electrode area were investigated. The absorption properties of newly used dye (Rhodamine B) were analyzed. This photogalvanic cell can be used for 85.0 min in dark. A mechanism of cell photochemical reaction has also been proposed.
