Polyacrylonitrile (PAN)-based polymer is a promising material to convert liquid electrolyte to gel state because of its high cation solvating ability and excellent mechanical strength. However, the PAN-based polymers exhibit poor solubility in acetonitrile (ACN) based solvent due to the strong dipole-dipole interaction among polymer chains. Copolymerization with other suitable monomers can solve the solubility problem and improve solvent retention ability. The PAN-based block copolymers, which are soluble in ACN solvent, can be highly effective materials as polymer gel electrolytes (PGEs) in quasi solid-state dye-sensitized solar cells (QSS-DSSCs). PAN-based PGEs can compete with liquid electrolytes in terms of photovoltaic performance and stability. Our developed PAN-based PGEs can be potential candidates for QSS-indoor DSSCs to power low light electronics and autonomous IoT devices commercially. For outdoor application, further enhancement of the stability of the device is required. |
