Layer‐by‐layer (LbL) deposition of polyelectrolytes is utilized to prepare solid‐state dye‐sensitized solar cells. Hydrophilic LbL films are treated at low pH to induce a microporous structure, and then infiltrated with TiO 2 by liquid‐phase deposition. The porous TiO 2 layer (see graphic) is sensitized with dye and then coated with a solid polymer electrolyte. The conversion efficiency of this solid‐state device is 1.1 %.
