Organometal halide perovskite solar cells (PSCs) are promisingly applied to flexible solar cells because of the high power conversion efficiency (PCE) and intrinsic softness of perovskite materials. In the most efficient PSCs, mesoporous TiO generally functions as the electron transporting layer. However, the mesoporous TiO is typically generated through high-temperature thermal annealing that is not suitable for producing flexible PSCs. In this work, TiO nanopillar arrays are directly deposited on flexible substrates using glancing angle deposition at low substrate temperature. The TiO nanopillars strongly adhere to the flexible substrates, improving light harvesting in the perovskite layers, facilitating electron extraction and transportation, and enhancing the mechanical flexibility of the PSCs. The flexible PSCs hybridized with the TiO nanopillars show a PCE as high as 13.3% and excellent photovoltaic stability after 500 cycles of bending at a small radius of curvature.
