Abstract

Quasi-solid state dye-sensitized solar cells(DSSCs) were prepared by using gel-state ionic liquid electrolytes containing layered titanates as gelator. These gelators were prepared by intercalating organic materials into interlayers of layered titanates and then dispersed within ionic liquid electrolytes. As a result, the quasi-solid DSSCs showed the enhancement of current density from 3(mA/cm2) to 4.5(mA/cm2) although the viscosity of electrolytes increased. The improvement of current density is explained by an increase in dissociation of ionic species as well as scattering effect of layered titanates.
