Formation of a crystalline nanotube–nanoparticle hybrid by post water-treatment of a thin amorphous TiO2 layer on a TiO2nanotube array as an efficient photoanode in dye-sensitized solar cells†
Abstract
An atomic layer deposited, conformal thin layer (∼15 nm) of amorphous TiO2 on a primary TiO2 NT array is effectively converted into partly crystalline
