UC Berkeley Researchers Develop Blue Light Emitting LED with Perovskite

Scientist at University of California, Berkeley (UC Berkeley) have created a blue LED from a new semiconductor material halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices. Published in Science Advances on January 24, the study demonstrates the technology breakthrough of applying the unstable material as halide perovskite changes with temperature, humidity and the chemical environment and their optical and electronic properties are thus disrupted. Making semiconductor diodes that emit blue light has always b...

Perovskite-based NIR LED Achieves Record Efficiency

An international research team has developed near-infrared (NIR) LED based on perovskite in a laboratory at Linköping University in Sweden which achieve a record external quantum efficiency of 21.6 percent Perovskites have good light-emitting properties and are easy to manufacture. However, the external quantum efficiency of perovskite-based LED has until now been limited due to defects that arise in the material during manufacture. The defects act as traps for the charge carriers and thus cause energy losses. (Image: Linköping University) To solve the ...
