In the past, scientists have discovered that perovskite particles can be used to produce high-efficiency solar cells, but the only problem is that it is difficult to make thin films based on perovskite particles.
Now this problem has been solved.
Barry Rand, assistant professor of electrical engineering from Princeton, said that the new technology we have developed allows these perovskite nanoparticles to self-assemble and eventually produce an ultra-fine grain film.
This makes the Perovskite LED capable of becoming a replacement for existing LED technology. The future will be based on this new technology is expected to produce brighter, cheaper display and television products. 
New Generation of LED Technology Success: Brightness Increases More Cheaply
In the past few years, LED lighting has been sought after in various fields of the world because of its more power saving and longevity.
Now, more efficient and cheaper LED technology is approaching people's lives.
