Solid State Electrolytes For Dye-Sensitized Solar Cells

Dye sensitized solar cells (DSCs) are promising alternative to conventional Si-based solar cells due to their low cost, easy fabrication and relatively high conversion efficiency. In the DSC, the electrolyte plays an important role in the regeneration of dye molecules and the charge transportation. Although the DSCs based on the liquid electrolyte can present much better photovoltaic performance, the disadvantages of the liquid electrolytes (i. e. volatility and easy leakage) are supposed to reduce the long-term stability. Therefore, the development of (quasi) solid-state electrolytes is necessary and imperative. In this paper, the recent progress on the solid-state electrolytes and the prospects are given.
