Homogeneous nanoporous TiO2 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.
