Novel cyclotetrasiloxane tetraimidazolium salts as high performance quasi-solid state electrolyte for dye-sensitized solar cells
A new type of quasi-state ionics based on cyclosiloxane imidazolium iodides was synthesized and used as electrolytes in dye-sensitized solar cells (DSSCs). The cyclosiloxane electrolyte formed a distinctive ca...
