Highly ordered 1D TiO 2 nanotube arrays are fabricated and applied as nanocontainers and electron transporting material in CH 3 NH 3 PbI 3 perovskite solar cells. The optimized device shows a power conversion efficiency of 14.8%, and improved stability under an illumination of 100 mW cm −2 . This is the best result based on 1D TiO 2 nanostructures so far.
