The photogalvanic effect was studied in photogalvanic cell containing orange G as Photosensitizer, sodium lauryl sulphate and EDTA as reducing agent. The photo-outputs with EDTA are higher for Solar Energy Conversion and Storage. The current-voltage relations of the cell have been measured in the dark and light under both forward and reverse direction. The photo potential and photocurrent generated was found to be 960.0 mV and 350.0 µA, respectively. The observed conversion efficiency was 1.52% fill factor and the maximum power of cell was 0.47 µA and 158.9 µW. The storage capacity of the cell was 80.0 minutes in dark. A mechanism was proposed for the generation of photocurrent in photo galvanic cell.

The studies of the micellar effect on photogalvanics were done for solar energy conversion and storage in photogalvanic cell containing sodium lauryl sulphate as anionic micellar species, ethylenediamine tetra acetic acid as reductant, and Safranine O as photosensitizer. The photopotential and photocurrent generated were 871.8 mV and 200.0 A, respectively. The observed conversion efficiency was 0.7213%, the fill factor was 0.35, and the maximum power of the cell was 174.2 W, whereas the power at the power point of the photogalvanic cell was 75.02 W. The rate of initial generation of current was 50.0 A min 1 . The photogalvanic cell can be used for 40.0 min in the dark. The effects of different parameters on the electrical output of the photogalvanic cell were observed and a mechanism was proposed for the generation of photocurrent in the photogalvanic cell.

The Magnolia Champaca flower extract was used as green photo sensitizer with CTAB-EDTA systems for the enhancement of the conversion efficiency and storage capacity of photo galvanic cell for its commercial viability. Natural photo sensitizer (Magnolia Champaca extract) has been studied to obtain some insight with aim of finding relatively cheaper, cost effective and eco friendly photo sensitizer for further improvement in the electrical performance of galvanic cell. The observed cell performance in terms of photo potential, photocurrent, fill factor and storage capacity are 1080.0mV, 90.0μA, 0.40 and 40.0 minutes, respectively. The effects of different parameters on electrical output of the cell were observed and a mechanism has been proposed for generation of the photo potential and photocurrent in photo galvanic cell. Keywords: Magnolia Champaca Extract, CTAB, EDTA, photo potential, photocurrent I.INTRODUCTION Energy is one of the most fundamental and essential for development of nations. Energy is the lifeline of the country's economy and development. Because of the increasing demand in clean energy, solar energy is clean and renewable. In present the solar energy industry is one of the growing forces in renewable energy system .The device, in which convert solar energy into electrical energy are called solar cells. As long ago as in 1839 Becquerel observed that light can cause changes in the current and voltage characteristics of certain electrochemical cells After four year this concept of dye sensitization was carried out by Meyer from photography to photo electrochemical cells .Photo galvanic cells are under preliminary research stage these have high conversion efficiency but lacks storage capacity and the latter are found to have good storage capacity but low conversion efficiency. The success of any solar cell depends upon its power conversion efficiency. However, the worldwide demand for energy is expected to keep increasing at 5 percent each year [1]. Nowadays there are several major directions for solar technology development for photo galvanic that system directly converts the solar energy into electrical energy. Becquerel [2] first observed in 1839 the flow of current between two unsymmetrical illuminated metal electrodes in sunlight. Later, it was observed by Rideal [3] and Rabinowitch[4.] A dye sensitized solar cell which is based on a semiconductor formed between a photosensitized anode and on electrolyte systematic investigation was done [5]. And a metal based photo galvanic solar panel is the most commonly used solar technology to generate electrical energy was studied [6]. Use of some reductant and photo sensitizer in photo galvanic cells for solar energy conversion and storage was investigated [7]. The studies of photo galvanic cell consisting various dyes with reductant and surfactant were done [8]- [9]. Recently the photo galvanic effect in various interesting system were observed [10]- [11]. The photo chemical conversion of solar energy into electrical energy was studied [12]- ...
