Innovative study for enhanced performance of the photogalvanic cells for solar energy conversion and storage

The main objective of the present research is to improve solar energy conversion and photogalvanic cell storage for power generation. In order to provide electricity to the entire planet, the scientific community worldwide is compelled to search for renewable energy sources that are both economically and environmentally feasible. Therefore, using solar energy to generate renewable energy is the best way to meet the country's energy needs. A digital pH meter, carbon pot, micro-ampere, resistance key, and specifically constructed H-shaped photogalvanic (PG) cell were employed in the investigation. A mixture of surfactants (NaLS + CTAB), reductant (Xylose), and dye-Methylene blue (MB) solution was used for the PG cell. Through the manipulation of various current parameters, the impact of solar energy was examined. The photopotential (PP) and photocurrent (PC) with mixed surfactant (CTAB+NaLS) system were measured at 702.00 mV and 237.00 μA, respectively. The PP and PC with single surfactant (CTAB) system were measured at 681.00 mV and 48.00 μA, respectively. The PP and PC with single surfactant (NaLS) system were measured at 635.00 mV and 90.00 μA, respectively. In the absence of light, the PG cell performance was determined at 90.00 minutes, yielding a conversion efficiency of 0.4327%. With a focus on improved electrical output and solar energy storage, it has been experimentally demonstrated that the mixed surfactants (NaLS+CTAB) in PG cells are the more effective system than single surfactant system.
