Abstract

We prepared dye-sensitized solar cells (DSSCs) with enhanced energy conversion efficiency using open-ended TiO₂ nanotube arrays with a TiO₂ scattering layer. As compared to closed-ended TiO₂ nanotube arrays, the energy conversion efficiency of the open-ended TiO₂ nanotube arrays was increased from 5.63% to 5.92%, which is an enhancement of 5.15%. With the TiO₂ scattering layer, the energy conversion efficiency was increased from 5.92% to 6.53%, which is an enhancement of 10.30%. After treating the open-ended TiO₂ nanotube arrays with TiCl₄, the energy conversion efficiency was increased from 6.53% to 6.89%, a 5.51% enhancement, which is attributed to improved light harvesting and increased dye adsorption.
