The study explores the photogalvanics of Sudan-I dye, fructose, and sodium lauryl sulfate in alkaline medium under low artificial sun intensity to find an optimal combination for enhancing cell efficiency. The results show significant improvement in cell performance, with key indicators such as solar conversion efficiency, open circuit potential, and charging time displaying impressive results.
With the rapid commercialization of wind and solar power generation, the need of power storage capacity is gaining importance. The photogalvanic cells as described in the present manuscript are promising energy devices as they provide for a route for simultaneous solar power generation and its storage. The study of photogalvanics of Sudan-I dye (photo-sensitizer)-Fructose (reductant)-Sodium Lauryl Sulfate (surfactant) has been done in alkaline medium at low and artificial sun intensity with aim of finding relatively better combination of chemicals like photosensitizer, reductant and surfactant for further enhancing the efficiency of these cells. This combination of chemicals has shown very impressive and surprisingly very high improvement in cell performance. The optimum conditions for cell have also been observed for optimal cell performance. The power at power point, solar conversion efficiency, open circuit potential, equilibrium current, charging time, and power storage capacity (as half time) at 10.4 mWcm(-2) (low and artificial illumination intensity) has been observed of the order of 367.8 mu W, 11.49%, 1014 mV, 1350 mu A, 21 min, and 30 min, respectively.
