Highly transparent and nanostructured nickel oxide (NiO) films through pulsed laser deposition are introduced for efficient CH 3 NH 3 PbI 3 perovskite solar cells. The (111)‐oriented nanostructured NiO film plays a key role in extracting holes and preventing electron leakage as hole transporting material. The champion device exhibits a power conversion efficiency of 17.3% with a very high fill factor of 0.813.
