A plastic substrate‐based dye‐sensitized photoelectrode was fabricated with a thin mesoporous titania film prepared on a TiO x ‐coated indium tin oxide‐polyethylene naphthalate (ITO‐PEN) substrate by a low‐temperature process. The 3.5 μm‐thick titania film sensitized with an indoline dye (D205) yielded a power conversion efficiency of 5.2 %, with the internal quantum efficiency reaching 100 %.
