In the present work, the studies in photogalvanics of indigo carmine dye with EDTA reductant and dioctyl sodium sulphosuccinate surfactant in alkaline medium has been done with aim of finding relatively better combination photosensitizer, reductant and surfactant for improvement in electrical performance of these cells. The photopotential and photocurrent were observed 920 mV and 410 μA, respectively. The conversion efficiency of the system was determined as 0.9377 % and fill factor 0.2530. The cell performance was observed 120 min in dark. The effects of different parameters on the electrical output of the cell were observed and current-voltage (i-V) characteristics of the cell were also studied in this dye surfactant cell combination.
