Highly Oriented Halide Perovskite Films
In article number 2305539, Johnny C. Ho and co‐workers propose a slow‐evaporating solvent (SE) method to fabricate high‐quality halide perovskite films. Compared with the conventional spin‐coating method, the perovskite films fabricated by this SE method shows much higher crystallinity and a highly oriented lattice, which endows them with superior photodetection...
Halide perovskites are potential next‐generation optoelectronic devices. However, the film quality of this charming material fabricated by the conventional spin‐coating method is far from satisfactory, significantly affecting the optoelectronic devices' performance. Here, one facile slow‐evaporating solvent (SE) method is demonstrated to synthesize high‐quality organic–inorganic halide perovskite...
