Metal halide perovskite has risen as a promising material for diodes which shines light. System efficiency has been enhanced mainly by optimizing the active and charging layers for injection during the past. Current high-quality LEDs are linked to direct bandgap semiconductors but it is not an easy job to make these devices since they need to be manufactured at extremely high temperatures and in vacuum, which makes them very costly for manufacturing in large numbers. They are inexpensive and simple to produce and thus can be easily tuned to emit light from a wide spectrum of colours, perovskites which are direct-bandgap semiconductors may be real alternatives to other kinds of direct-bandgap materials for applications including colour displays. All these processes are done by mixing solutions and heating up the solution by a certain temperature. Having this known knowledge or concept, some of the materials could be done onto certain numerous substrates. The method implemented is known as Microwave Irradiation Method for perovskites LEDs.
