Abstract
A non-volatile composite electrolyte consisting of TiO2 hollow spheres for dye-sensitized solar cells (DSSCs) is prepared and the effect of the hollow spheres on the performance of DSSCs with non-volatile electrolytes is investigated. The TiO2 hollow spheres of various mean diameters prepared by template method was mixed with PEGDME oligomer, showing a successful construction of electrolytes suitable to DSSCs without any problem. Applying the TiO2 hollow spheres to the DSSCs with non-volatile oligomer electrolytes, the solar cells exhibit highly enhanced quantum efficiency, demonstrating that the presence of TiO2 hollow spheres has a large advantage to improve the ion diffusion of DSSCs with non-volatile electrolytes as well as to donate additional light harvesting effect at longer wavelength of light
