Organic Light-Emitting Diodes Combining Thick Inorganic Perovskite Hole Transport Layers and Ultrathin Emitting Layers

Organic light-emitting diodes have a huge gain in popularity over the past 25 years for display and lighting applications, but the production of low-cost efficient devices remains a challenge. OLEDs using sub-nanometer undoped emissive layers are a route to fabricate cost-effective devices but, as they are inherently thin, it opens to issues with variation in […]
