Eliminating Redox Electrolyte: A Conceptual Study on Optimizing the Electric Potential Energy Generation of a  Simplified DSSC Design 

Kirsten Nicole T. Segismundo 

Dye-sensitized solar cells (DSSCs) offer a cost-effective and efficient alternative to conventional photovoltaics. Still, their reliance on liquid redox electrolytes makes it difficult to replicate as it is a solution that is not easy to acquire. Liquid redox electrolytes also lead to leakage, evaporation, and long-term instability. This study explores a conceptual approach to see whether making a functional dye-sensitized solar cell without electrolytes is possible. It investigates possible modifications and steps to manipulate the remaining components of the DSSC, the conductive glass, TiO2 paste, and natural dye, for it to reach optimum efficiency. The research reviews existing DSSC technologies, studies, and procedures to assess the viability of an electrolyte-free design. This study contributes to advancing eco-friendly DSSCs by addressing stability and sustainability concerns. Addressing this gap could pave the way for more stable, low-cost, and sustainable solar cell technologies. A deeper investigation regarding charge transport and future experimental validation is recommended to determine the practicality of this approach.
