Dye-sensitized solar cells (DSSCs) are attractive candidates for the next generation of solar energy conversion. Owing to their low-cost materials

simple fabrication process and high energy conversion efficiencies and so on

dye-sensitized solar cells possess broad research interests and great potentially commercial applications. A DSSC typically consists of a dye-adsorbed photoelectrode layer

a counter electrode

and electrolyte. The electrolyte

as one of the key component in DSSCs

would have a significant influence on ions diffusion

charge transport and dye regeneration

thus affecting photovoltaic performance of DSSCs. In this review

we mainly focus on recent research developments of quasi-solid-state dye sensitized solar cells. Three aspects including polymer gel electrolytes

low molecular mass organic gelator and inorganic nano-particle gel electrolytes are highlighted. Finally

the future research trend of quasi-solid-state electrolyte for enhanced DSSCs is also prospected.
