Title: Contact passivation for perovskite optoelectronics
Inventor: TAN HAIREN
IPC: H01L31/04

Abstract: Title: CONTACT PASSIVATION FOR PEROVSKITE OPTOELECTRONICS (57) : Disclosed herein are perovskite based optoelectronic devices made entirely via solution-processing at low temperatures (<150°C) which pro- vide for simple manufacturing, compatibility with flexible substrates, and per- ovskite-based tandem devices. These perovskite based optoelectronic devices are produced using an electron transport layer on which the perovskite layer is formed which is passivated using a ligand selected to reduce electron-hole re- combination at the interface between the electron transport layer and the per- ovskite layer.
