제목 High Efficiency Quasi-Solid-State Dye-Sensitized Solar Cells UsingLiquid Crystals-Embedded Quasi-Solid-State Electrolytes
초록 A new series of liquid crystal-embedded quasi-solid-state electrolytes were developed for obtaining high efficiency of quasi-solid-state dye-sensitized solar cells (DSSCs). The quasi-solid-state electrolytes were composed of iodide and tri-iodide redox species embedded in polyacrylonitrile (PAN) as a polymer matrix and liquid crystals (E7 or ML-0249). The liquid crystal-embedded quasi-solid-state electrolytes exhibited ionic conductivity of 4.7x10-3 S/cm and showed higher efficiency than the only PAN-based electrolyte. Highest efficiency of 6.21 and 6.29 % was obtained for the quasi-solid-state DSSCs for E7 to PAN and ML-0249 to PAN, respectively. These high efficiencies of quasi-solid-state DSSCs are due to the effective formation of pathway through liquid crystal orientation for the transport of redox species.
