preparation example Construction

[0060] see image 3, the synthesis method of the perovskite type material of one embodiment, comprises the following steps:

[0061] Step S110 : providing a synthesis device for the perovskite type material.

[0062] The synthesis device in step S110 is the synthesis device of the perovskite type material in the above embodiment, and details are not described herein again.

[0063] Step S120: adding a polar solvent to the first reaction vessel, adding a non-polar solvent to the second reaction vessel, adding solid powder to the injection piston, and adding a stabilizer to the vessel.

[0064] Wherein, the polar solvent is at least one selected from N,N-dimethylformamide, dimethylsulfoxide, tetrahydrofuran and N-methylpyrrolidone. The non-polar solvent is selected from at least one of o-xylene, toluene and chloroform. It can be understood that the polar solvent and the non-polar solvent are not limited to the above-mentioned ones, and may also be polar solvents and non-polar...

Embodiment 1

[0080] The synthesis process of the perovskite type material of the present embodiment is as follows:

[0081] (1) Add 2g of mixed powder (molar ratio of lead bromide and cesium bromide is 1:5) in the solid injection piston in advance, add a sufficient amount of oleic acid in the first vessel, and add a sufficient amount in the second vessel oleylamine, 15 mL of N,N-dimethylformamide was added to the first reaction vessel, and 50 mL of o-xylene was added to the second reaction vessel.

[0082] (2) add 1mL oleic acid and 1mL oleylamine to the first reaction vessel by computer control the first syringe pump and the third syringe pump respectively, and control the movement of the screw guide rail by the computer to push the injection piston to add in the first reaction vessel Solid powder 0.5g.

[0083] (3) The temperature of the first heating stirrer is controlled by a computer to be 60 degrees Celsius, and the rotating speed is 700 r / min. When the solution in the first reacti...
