The inherent limitations of liquid electrolytes - including leakage, volatility, and thermal instability - have driven the development of solid-state electrolytes (SSEs) for flexible dye-sensitized solar cells (DSSCs). This systematic review evaluates recent advances (2021-2024) in SSE technologies through comprehensive analysis of 30 peer-reviewed studies identified via PRISMA methodology across Scopus and Web of Science. Three key innovation pathways emerge: (1) polymer/gel electrolyte formulations achieving ionic conductivities up to 15.7 mS/cm, (2) hybrid architectures incorporating nanomaterials and liquid crystals, and (3) bio-derived electrolytes from sustainable sources. While maximum reported power conversion efficiencies reach 10.34% in optimized systems (average 7.2±1.8% across studies), critical challenges remain in ion transport kinetics (typically 1-10 mS/cm) and manufacturing scalability. The analysis identifies interfacial engineering and novel composite materials as priority research directions to bridge the performance-reliability gap for commercial deployment. These findings provide a strategic roadmap for developing next-generation flexible photovoltaics that combine high efficiency (>8% target) with mechanical durability.
