Rapid technological progress in white light-emitting diodes and its source in innovation and technology spillovers
Nature Energy, Published online: 25 April 2025; doi:10.1038/s41560-025-01757-1From 2003 to 2020, the efficiency of white light-emitting diodes rose from 6% to 39%, while costs fell by 96%. Weinold et al. explore the drivers of such rapid progress to formulate lessons for future clean energy innovation.
