Used as an ionic liquid in dye-sensitized solar cells (DSSCs) to improve conductivity and stability of the electrolyte. Enhances photovoltaic performance by facilitating efficient iodide/triiodide redox cycling. Also serves as a precursor for synthesizing other imidazolium-based ionic liquids used in electrochemical applications. Applied in catalysis and organic synthesis due to its low volatility and high thermal stability. Suitable for use in green chemistry processes where non-aqueous, polar media are required.
