Photo-enhanced growth of lead halide perovskite crystals and their electro-optical properties.

ABSTRACT: Organic-inorganic hybrid perovskites have attracted much attention for opto-electronic applications due to their low trap density, strong light absorption, and superior charge transport performance. Generally, the high efficiency of perovskite electro-optical thin films depends on their high-quality perovskite single crystals. In this work, the external illumination is applied on the perovskite single crystals growing in solution. It was shown that larger size CH₃NH₃PbI₃ single crystals can be obtained under illumination conditions. In addition, CH₃NH₃PbI₃ films are prepared by a one-step spin coating process under illumination, the crystal size and film quality of which have been obviously improved due to the effect of illu
