Researchers at Linköping University have highlighted cost, technical performance, and environmental impact as key factors for a new type of LED technology to make a commercial impact. Perovskite LEDs are seen as the next generation of LED technology, offering vibrant colors and easier manufacturing. However, concerns about toxic materials like lead and gold production have been raised. The study conducted by the researchers focused on the environmental impact and cost of different perovskite LEDs. The potential for commercialization of perovskite LEDs in the long term is promising, with efforts being made to increase their life expectancy to have a positive environmental impact.
