Ionic Liquid-based Polymers and Crystals for Dye-sensitized Solar Cells

Dye-sensitized solar cells (DSSCs) have been extensively investigated as a potential renewable power source because they do not rely on expensive or energy-intensive processing methods. Within a DSSC, the electrolyte is very important as it provides the ionic conductivity for charge transport between the photoanode and the cathode, as well as sets the potential barrier necessary for energy conversion. Considering the durability of DSSCs in practical applications, ionic liquids (ILs) have become the most promising electrolyte materials due to their advantages of negligible vapor pressure, high thermal stability, wide electrochemical window, and high ionic conductivity. Recently, great progress has been made in the development of solid-state ILs to avoid the fluidity and potential leakage of IL-based electrolytes during long-term operation under solar light illumination. This chapter reviews some of the key research on the topic of solid-state ILs using polymeric ILs or IL crystals for DSSCs, and some of the relevant literature has also been briefly introduced.
