In photogalvanic cells, electron transfer reactions can lead to the inexpensive production of solarpower with an inherent storage capacity because in solution, the ions involved act as mobile chargesthrough diffusion. This study improved the storage capacity and solar power of photogalvanic cellscomprising ethylenediamine acetic acid (EDTA), toluidine blue and sodium lauryl sulphate (NaLS) asa reductant, photosensitizer and surfactant, respectively. The observed maximum photocurrent,photopotential, and open circuit voltage, of the photogalvanic cell were 150 A, 743 mV and 1065 mV,respectively. The efficiency of conversion cells was approximately 0.2630%. In the dark, the storagecapacity (t0.5) was 124 min for the photogalvanic cell. The optimization of the influence of differentparameters such as variation in photosensitizer concentration, surfactant, reductant, pH, and temperatureas well as the electrical output was performed. A mechanism was proposed for photocurrent generationin the photogalvanic cell.
