Carbonaceous allotropes modified ionic liquid electrolytes for efficient quasi-solid-state dye-sensitized solar cells.

Highlights: [•] Ionic liquids (ILs) were modified and used in dye-sensitized solar cells (DSSCs). [•] Various carbon derivatives were added in the IL electrolytes. [•] Carbon derivatives provided the additional pathway for charge transportation. [•] Efficient quasi-solid-state DSSCs were achieved by using CYC-B6S dye. [ABSTRACT FROM AUTHOR]
