Abstract
Perovskites, widely-known for their promise in solar photovoltaics, also show promise in the realization of light-emitting diodes. Multiple classes of materials and emission wavelengths have now exceeded EQEs of 20%. Much effort has been invested in achieving charge transport layers that invest efficiently into these devices. Brightnesses are now reaching interesting levels for applications in information display. A key gating item is to advance further the understanding of degradation mechanisms, and to lever this understanding to extend operating lifetimes, just as the OLED community did two decades ago. I will review progress and open questions.
