An organic molecule makes the perovskite crystal more stable, says Heyong Wang, PhD student at the Department of Biomolecular and Organic Electronics. Researchers at Linkoping University, working with colleagues in Great Britain, China and the Czech Republic, have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability. The result has been published in Nature Communications. "Light-emitting diodes based on perovskites are still not suffi...
