Get attached : The mechanical attachment of TiO 2 nanotube layers to a substrate can be a determining factor for the performance of these layers in dye‐sensitized solar cells (DSSCs). Self‐organized TiO 2 nanotube layers grown in an electrolyte that contained lactic acid are shown to have considerably improved anchoring on the Ti metal substrate, which allows the construction of stable and efficient solar cells with >50 μm nanotube length (see figure).
