Supercomputer simulations make groundbreaking discovery about potential of solar power and LEDs: ‘Never been observed before’

Scientists from the Texas Advanced Computing Center are gaining a deeper — on the

— understanding about why perovskites are such a good material for converting sunlight into electricity.

The breakthrough was discovered using a supercomputer that found “vortex structures in quasiparticles of electrons and atoms, called polarons,”

to a summary, which is heavy on labspeak.

The important thing for energy users across America is that the findings could help to develop new solar cells and LED lighting that have the potential to “reshape the future of illumination,” the experts claim.

“These polarons show very intriguing patterns. The atoms rotate around the electron and form vortices that had never been observed before,” study co-author Feliciano Giustino, who is the director of the Center for Quantum Materials Engineering at the Oden Institute in Texas,

The polarons, or “lumps of charge … endow perovskites with peculiar properties,” per Giustino.

In what must be a fascinating scene, the polaron atoms swirl around electrons to form vortexes. The electrons become excited when they are hit with light photons. The vortexes may help to keep them that way longer, per the summary.

“We suspect that this strange vortex structure prevents the electron from going back to the unexcited energy level,” Giustino

Giustino said that his team’s findings would not have been possible without highly advanced computers, which helped to identify polarons and the unique way they, electrons, and photons interact in perovskite.
