Abstract

We report the increase in optical absorption in a finite three-dimensional photonic crystal through the dependence of the crystal film’s thickness. Varying thicknesses of ${\text{TiO}}_2$ inverse opal electrodes were assembled in dye-sensitized solar cells and their optical properties were characterized. Through measuring the enhancement in the incident photon-to-electricity conversion efficiency over the reference cell, we show that optical absorption of a photosensitive dye coupled to a finite ordered structure can be influenced by the spatial properties of the structure. This report provides an insight into the changes in optical absorption of an atom when the space surrounding that atom is modified.
