Dye-sensitized solar cells (DSSCs) have attracted considerable interest because of their high conversion of sunlight to electricity and lower production and material cost. A new series of liquid crystal-based polymer gel electrolytes were developed for obtaining the high efficiency of quasi-solid-state dye-sensitized solar cells (DSSCs) applications. The polymer gel electrolytes were composed of iodide and tri-iodide redox species embedded in polyacrylonitrile (PAN) as a polymer matrix and liquid crystals (E7 or ML) for increasing the order parameter of electrolyte components. The liquid crystal-contained polymer gel electrolytes showed higher photocurrent and photovoltage than the only PAN electrolyte. Highest efficiency of 6.21 % at 1 sun (6.94 % at 0.43 sun) was obtained for the quasi-solid-state DSSCs with 3:1 ratio of E7 to PAN under AM 1.5G illumination and an aperture mask condition. The verification of the role of the liquid crystals in the polymer gel electrolyte was performed with measurement of the electro-optical response of quasi-solid-state DSSCs under cross-Nicole polarizers.
