[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...
