Organometallic halide perovskite materials make great achievements in optoelectronic fields, especially in solar cells, in which the organic cations contain amine components. However, the amine with N-H bonds is easily hydrolyzed with moisture in the air, weakening the perovskite materials stability. It is desirable to develop other non-amine stable perovskite materials. In this work, sulfur-based perovskite-like (CH3)(3)SPbI3 nanorod arrays were fabricated by a solution-processed method, which can be indexed hexagonal crystal structure in the space group P63mc. The binding force is exceptionally strong between the non-amine (CH3)(3)S+ and PbI6 octahedral, leading to high stability of (CH3)(3)SPbI3. The (CH3)(3)SPbI3 nanorod arrays can keep the morphology and crystal structure in an ambient atmosphere over 60 days. In addition, the (CH3)(3)SPbI3 nanorod arrays can offer direct charge transfer channels, which show excellent optoelectronic properties. The (CH3)(3)SPbI3 nanorod arrays-based solar cells with VOx hole transfer layers achieved a power conversion efficiency of 2.07% with negligible hysteresis. And the (CH3)(3)SPbI3 nanorod arrays were also effectively applied in photodetectors with interdigitated gold electrodes. This work demonstrates that sulfur-based perovskite-like (CH3)(3)SPbI3 is a novel promising stable compound with great potential for practical optoelectronic applications.
