Homogeneous nanoporous TiO 2 films with controlled architecture, porosity, and layer thickness (see figure) have been prepared by the sol–gel methodology to optimize the efficiency of solid‐state dye‐sensitized solar cells. Using regioregular poly(3‐octylthiophene) as a hole conductor, a high solar‐conversion efficiency associated with excellent stability under light and air exposure has been achieved.
