Next generation LEDs are cheap and sustainable

“Perovskite LEDs are cheaper and easier to manufacture than traditional LEDs, and they can also produce vibrant and intense colours if used in screens. I’d say that this is the next generation of LED technology,” says Feng Gao, professor of optoelectronics at Linköping University. However, for a technological shift to take place, where today’s LEDs are replaced with those based on the material perovskite, more than just technical performance is required.

They specialise in how innovations contributing to environmental sustainability can be introduced to the market. Together, they have investigated the environmental impact and cost of 18 different perovskite LEDs, knowledge that is currently incomplete. The study was conducted using so-called life cycle assessment and tech ... Read full article.
