Abstract

The present work reports a rapid and facile method to fabricate a novel double-layer TiO₂ photoanode, which is based on highly ordered TiO₂ nanotube arrays and monodispersive scattering microspheres. This double-layer TiO₂ sphere/TNTA photoanode have got many unique structural and optical properties from TiO₂ scattering microspheres, such as high specific surface area, multiple interparticle scattering, and efficient light-harvesting. Results indicate that this as-fabricated double-layer TiO₂ sphere/TNTA front-illumination dye-sensitized solar cell, which is fabricated from the TiO₂ nanotube arrays with a 17.4 μm length after TiCl₄ treatment, exhibits a pronounced power conversion efficiency of 7.24% under an AM1.5 G irradiation, which can be attributed to the increased incident photon-to-current conversion and light-harvesting efficiency.
