RESUMO
Actual plan of research work was proposed for systematic investigating in the field of photogalvanic (PG) cells for solar energy transformation. It was necessary and proposed to carry out experimental work under the solar parameters for PG cells. The object of the research work is to enhance the solar energy conversion into electricity and store it through PG cells. Various parameters were studied in a PG cell having D-Xylose + MB + Brij-35 + NaLS system (mixed surfactants). In this study, the observed optimum results in terms of the open circuit voltage, photopotential, maximum photocurrent, and short circuit current are 921.00 mV, 698.00 mV, 311 uA, and 245.0 uA, respectively. The observed equilibrium photocurrent, current at power point, fill factor, and conversion efficiency were 243.0 uA and 142.0 uA, 0.4521, and 0.6769%, respectively. For individual surfactants, the observed results in terms of the open circuit voltage, photopotential, maximum photocurrent, and short circuit current are 870.00 mV, 635.00 mV, 175 uA, and 90.0 uA, respectively. For individual surfactant system, the observed equilibrium photocurrent, current at power point, fill factor, and conversion efficiency were 84.0 uA and 55.0 uA, 0.3630, and 0.3100%, respectively. The impact of solar energy was studied by varying the various parameters in PG cells. On the basis of above obtained values, the mixed surfactants (NaLS + Brij-35) have experimentally proved the efficient system as the desired object of research with special reference to enhance electrical out and storage of solar energy.
