Electrolye in Dye-Sensitized Solar Cells/ Part A: Liquid Electrolytes

In recent years, dye-sensitized solar cells have been considered for low cost and availability for conversion of solar energy to electrical energy. Dye-sensitized solar cells have varied componenets, one of the main components of this devices is electrolyte. Electrolytes play the role of electron-hole generation to return dye-molecules to the grand state. An important group of electrolytes is liquid electrolyte that the most famous of these is iodide/triiodide. Generally, a liquid electrolyte contains three main componenets of the solvent, ionic conductors and additives. The aim of this article is introduce and describe the components of the liquid electrolye including manterials and components. Finally, some brief oulook and performance of the liquid electrolytes are presented.
