A new method of producing high‐quality perovskite films via sequential deposition is presented , introducing a PbX 2 capping layer that is endowed with a network of interconnected nanopores. The mesoporous lead halide architecture provides a powerful tool to accomplish rapid and complete transformation of lead halide into the perovskite for high‐efficiency solar cells.
