Claim 0:
1. A method of manufacturing a perovskite light-emitting diode, comprising steps of:
providing a substrate;
disposing a first electrode layer on the substrate, wherein the first electrode layer is formed by vacuum evaporation;
disposing a hole transport layer on the first electrode layer;
disposing a perovskite precursor liquid layer on the hole transport layer;
coating the perovskite precursor liquid layer with a first solvent, performing a first thermal process on the perovskite precursor liquid layer coated with the first solvent, and allowing the perovskite precursor liquid layer to form a perovskite prefabricated layer;
coating the perovskite prefabricated layer with a second solvent, performing a second thermal process on the perovskite prefabricated layer coated with the second solvent, and allowing the perovskite prefabricated layer to form a perovskite light-emitting layer; and
disposing an electron transport layer and a second electrode layer sequentially on the perovskite light-emitting layer;
wherein durations for the first thermal process and the second thermal process range from 10 minutes to 120 minutes.
