Single crystal reflects the intrinsic physical properties of a material, and single crystals with high-crystalline quality are highly desired for acquisition high-performance devices. We found that large perovskite CH3NH3PbI3(Cl) could be grown rapidly from chlorine-containing solutions. Within 5 days, as 20 mm × 18 6 was harvested. As most important index to evaluate crystalline quality, full width at half-maximum (fwhm) in high-resolution X-ray rocking curve (HR-XRC) as-grown measured arcsec, which is far superior so reported CH3NH3PbI3 (∼1338 arcsec). The unparalleled delivered low trap-state density down 7.6 108 cm–3, high carrier mobility 167 ± 35 cm2 V–1 s–1, long transient photovoltaic lifetime 449 76 μs. improvement together rapid growth rate excellent transport property, provides state-of-the-art hybrid materials optoelectronic
