Recent advances in solar cell technology have been motivated by new materials and inventive engineering techniques. Dye‐sensitized solar cells (DSSCs) are becoming more widely recognized as a possible alternative for sustainable energy. Optimizing electrolytes is one of the most important variables impacting their effectiveness and durability. The electrolyte interface is critical to optimize charge separation, ion transport, and diffusion ensuring device stability and efficiency. The present investigation focuses on enhancing interface stability and investigating innovative electrolyte compositions to improve DSSC performance for sustainability in solar energy applications. Despite progress, obstacles remain in presenting core principles and research approaches in DSSC technology. Continued research is required to overcome these limitations and fully realize the potential of DSSCs in sustainable energy solutions.
