Enhanced Photogalvanic Cell for Solar Energy Using Neutral Red, DTAB, and Cellobiose in Alkaline Solution

Abstract

This study details a comprehensive investigation into the photogalvanic properties of a stable Neutral Red non-ionic dye photosensitizer system. It has been conducted in the presence of Dodecyl trimethyl Ammonium Bromide (DTAB) surfactant and cellobiose reductant within an alkaline medium, with the primary aim of advancing solar energy conversion and storage capabilities. The novelty of this research is the substantial improvement in electrical performance achieved compared to prior photogalvanic cell studies. The optimized system demonstrated impressive metrics, including a maximum potential of 916 mV, a maximum current of 10000 µA, a power at power point of 847 µW, a fill factor of 0.26, and a conversion efficiency of 10.95%. These high-performance indicators underscore the practical relevance of the study and its potential to contribute to more efficient photogalvanic technology. The achieved performance is attributed to the meticulous optimization of various cell fabrication parameters, leading to a synergistic enhancement of the system's overall efficiency and stability.
