High‐Temperature Solid‐State Dye‐Sensitized Solar Cells Based on Organic Ionic Plastic Crystal Electrolytes

Organic ionic plastic crystal, 1-ethyl-1-methyl pyrrolidinium iodide (P12I), is employed as the solid-state electrolytes for dye-sensitized solar cells. The fabricated solid-state devices show an overall power conversion efficiency of ∼5.8% under AM 1.5 radiation (50 mW/cm2) and excellent long-term stability at 80 °C.
