摘要

The stability of single-crystalline/monocrystalline-like perovskite film is expected to be better than its microcrystalline counterparts. In the present work, highly orientated perovskite thin films (CH3NH3PbI3-xClx) are prepared by means of aquointermediates assisted solution process. It displays super-duper preferred-orientation along < 110 > direction that is close to the single crystal, and its diffraction intensity ratio of (110)/(310) is nearly two orders of magnitude higher in contrast to the films that prepared by traditional way. Owing to its superior performances, e.g., highly crystallized quality, stress-free inside films, longer electron lifetime, faster temporal response time, etc., the highly orientated perovskite-based solar cells accordingly allow realizing high efficiency while improving its thermal stability.
