Stacked ZnO structures made of a nanoporous film superimposed on a dense underlayer have been prepared by electrochemical deposition on fluoride doped SnO 2 substrates. The growth conditions of the two components have been optimized in order to get efficient photoelectrodes after sensitization by the D149 metal‐free indoline dye. From the dye‐sensitized solar cell characteristics, the optimal underlayer and nanoporous layer deposition times have been determined. Moreover, the porosity induced by the use of an organic structure directing agent, eosin Y, has been found optimum for a concentration of 50 μM.
