摘要： Provided are an electrolyte composition of a dye-sensitized solar cell, a manufacturing method thereof, and a dye-sensitized solar cell comprising the composition. The composition comprises a polyvinylidene fluoride (PVDF) based high polymer and titanium dioxide nanoparticles serving as an inorganic material based filler. Using the PVDF based high polymer in the composition can solidify the composition, and this solidification can contribute to the flexibility of a solar cell. Also, the inorganic material based filler, i.e., the titanium dioxide nanoparticles, can reinforce the collection and retention of an aqueous component comprising iodide ions, which are carriers within the electrolyte. Accordingly, compared to typical high polymer based electrolyte solutions, excellent photoelectric conversion efficiency can be achieved with the above electrolyte composition.
