Abstract

Dye sensitized solar cells (DSSC's) are constructed using TiO2 electrodes synthesized by aqueous liquid phase deposition in combination with microcontact printing techniques or porous thin film template methods. Layer-by-layer deposition of polyelectrolytes is used to produce an ionic conducting solid-state electrolyte thin film, which is enhanced by post-processing in oligoethylene glycol diacid (OEGDA). The impact of TiO2 film architecture, as well as the thin film electrolyte, on device performance is discussed.
