In a major breakthrough, researchers have developed a method to use femtosecond laser ablation to produce high-quality crystalline perovskites. The method, developed by a team of researchers from the University of Tokyo, involves using a few-cycle laser to ablate a perovskite crystal with a pulse duration of less than 10 femtoseconds. The resulting crystal structure was found to be highly crystalline and uniform, with a very low defect density. The team believes that their technique could be used to produce perovskites for various applications, including photovoltaics, optoelectronics and light-emitting diodes. This development could potentially revolutionize the fabrication of perovskite crystals and enable the development of a wide range of new technologies.
