However, the best-performing devices are often made from lead (Pb)-based perovskites, whose toxicity may cause potential environmental concerns. To resolve the toxicity problem, an effective method has been the use of tin (Sn) as a partial or full replacement of lead in the perovskite materials. This strategy has been particularly successful for perovskite solar cells. However, tin-based (including tin-lead) perovskite materials are generally very poor light emitters, causing unsatisfactory performance of tin-based perovskite light-emitting devices (LEDs).&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-08-germanium-lead-perovskite-toxicity.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Germanium-lead perovskite LEDs: A new way to reduce toxicity<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Metal-halide perovskites are a new class of semiconductor materials for LED display and solar-energy harvesting.
