Starting materials: CH3NH3PbI3, lead (II) acetate, CH3NH3+ (by adding a 40% solution of CH3NH2 in water), concentrated HI
Product: Black and opaque MAPbI3 Single crystal
Description: CH3NH3PbI3 was synthesized from lead (II) acetate and CH3NH3+ (by adding a 40% solution of CH3NH2 in water) dissolved in concentrated HI solution. Cool aqueous solution from l00°C to not lower than 40°C to obtain a black crystal. Crystals of about 1 cm in dimension were obtained. Synthesis using reference [2].

Method: Single crystal X-ray diffraction
Description: Spherical samples were cut and polished into 0.3mm in diameter, among which a single crystal was selected and was mounted on an off-centered 4-circle diffractometer (HUBER 424) controlled by MXC (Mac Science). Graphite-monochromated Mo K\alpha radiation was used from a rotating anode generator with 50 kV–250 mA. Refer to Page 1695 Table I (Params); Page 1696 Table II (Apos).
