A new method of producing high-quality perovskite films via sequential deposition is presented, introducing a PbX₂ 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.
