Outline of Final Research Achievements

In this study, for the purpose of up-conversion of dye-sensitized solar cell (DSSC), we fabricated the DSSC photoelectrode with the light scattering layer constituted of core-shell particles. As the materials of shell moiety of core-shell microbead, high refractive index inorganic materials, i.e., CeO2, TiO2 and ZrO2 were adopted. Poly acrylic ester spherical microbead as core matrix was surface-modified with above-mentioned inorganic materials by an electrostatic interaction. In DSSCs, the light scattering layer constituted of the core-shell particles were arranged onto the reverse side of semiconductor layer to which the dye was adsorbed. As results, the remarkable increase in the short circuit photocurrent density Jsc and conversion efficiency η (%) in novel DSSC with light scattering layer constituted of core-shell microbeads was confirmed relative to that of conventional DSSCs cell.
