A novel, sandwich‐layered Ti/TiO 2 /Ti/fluorine‐doped tin oxide (FTO) architecture is reported. The Ti layers play a critical role in the formation of long pear‐necklace chains made of interconnected TiO 2 nanoparticles. The chains interpenetrate a network structure on FTO glass substrates under alkaline hydrothermal‐processing conditions. A significant enhancement in the photocurrent density of dye‐sensitized solar cells employing non‐volatile polymer‐based electrolytes is obtained.
