摘要：

A new series of liquid crystal embedded in polymeric electrolytes was developed for obtaining high efficiency in quasi-solid state dye-sensitized solar cells (DSSCs). The polymeric electrolytes were composed of iodide and tri-iodide redox species in polyacrylonitrile (PAN) as a polymer matrix and liquid crystals (E7 or ML-0249) for increasing the order parameter of electrolyte components with easy transport of redox species. The highest efficiency (6.21 and 6.29% at 1 sun) was obtained for the quasi-solid state DISKS using E7 to PAN and ML-0249 to PAN, respectively, under AM 1.5 G illumination and an aperture mask condition. The high efficiencies of the quasi-solid state DSSCs are due to the effective formation of pathways through liquid crystal orientation for the transport of redox species.
