英文摘要： Based on research and development of quasi-solid dye-sensitised solar cells (DSSC), thixotropic quasi-solid electrolyte is constructed through nanometer synthesis technology. Its mechanical thixotropy can enhance the ion transport capacity, permeability and filling ability of quasi-solid electrolyte in the nanoporous films, which must improve photoelectric conversion efficiency of quasi-solid DSSCs and the stability of the devices, which provides theory and practice on the research and application of DSSCs. Thixotropic quasi-solid electrolyte is constructed by employing a nanocomposite inorganic sol with narrow size distribution and uniform dispersion made by the sol-gel method or other synthesis methods, by mixing ionic liquid, active redox electric couple and other components. Thixotropy structure model of quasi-solid electrolyte is established by characterization on the ionic transfer capability, stability and liquidity, with permeability and filling ability in the nanoporous film. Multiple composite anode films with different grain sizes or grain morphologies are constructed by mixing with nano-powder of different sizes or 1-D nano powder (titanium oxide nanorods or nanotubes) is synthesized. The chemical structure, porosity, surface area and structure of nano-powder and films are characterized through the S
