A new crystal form of 1D perovskite (pyrrolidinium)PbI 3 (orthorhombic phase) is synthesized and characterized. The 1D perovskite has a good film formability by solution spin coating and is in situ transformed to 3D CH 3 NH 3 PbI 3 via the organic cation exchange approach in CH 3 NH 2 atmosphere, which is dense and uniform. The converted 3D perovskite film is used as a light absorber, and the corresponding perovskite solar cell shows a power conversion efficiency of up to 19.2% under simulated 1 sun AM1.5G illumination (100 mW cm −2 ).
