An anodized TiO₂ interconnected network was fabricated and utilized as a mesoporous scaffold and electron transporter in perovskite solar cells. By modifying the synthesis parameters, the morphological features of the interconnected TiO₂ nanostructures can be widely tuned and precisely controlled. The functional properties of the anodized TiO₂ network are found to be severely influenced by morphology as well as the extent of oxidation. The device with the optimized TiO₂ network exhibits superior electron extraction and transferability, resulting in conspicuous enhancement of the photocurrent and power conversion efficiency (PCE). This work proposes a promising and facile method for improving the performance of perovskite solar cells.
