19_07b/2009Inverse-Opal Electrodes: Compact Inverse-Opal Electrode Using Non-Aggregated TiO2 Nanoparticles for Dye-Sensitized Solar Cells (Adv. Funct. Mater. 7/2009)

On page 1093, Hyunjung Lee and co-workers report a novel method to fabricate an inverse-opal electrode for dye-sensitized solar cells. Compact and ordered TiO2 inverse-opal photoelectrodes are prepared using a 3D colloidal array templating route with flexible dimensional control of pore size. Organic-layer-coated TiO2 nanoparticles improved the degree of infiltration and consequently minimized the volume contraction during thermal calcinations of the colloidal template within the inverse opal structure.
