| titleOfInvention | A kind of method of quick preparation large area perovskite crystal |
| abstract | The invention belongs to Semiconductor Optoeletronic Materials and device preparing technical field, disclose a kind of method of quick preparation large area perovskite crystal.This method includes the following steps：A certain amount of lead halide and methyl ammonium halide are weighed, is mixed, then adds in Isosorbide-5-Nitrae fourth lactones, dissolving obtains perovskite solution；Then gained perovskite solution is added in a certain amount of organic solvent, perovskite crystal is precipitated to obtain.Perovskite crystal is quickly precipitated by way of solution extracting in the present invention, this method is simple and practicable, it is reproducible, to extraneous of less demanding, but also different organic solvents can be selected to grow to obtain the single crystal grain of different sizes according to actual demand, its crystal grain sizes maximum is up to tens micro-meter scales so that it is making advantage of the photoelectric device etc. with bigger. |
