ACS Energy Lett. 2022 Oct 14;7(10):3653-3655. doi: 10.1021/acsenergylett.2c01773. Epub 2022 Sep 30.

ABSTRACT

Lead-free PEA2SnI4-based perovskite LEDs are successfully inkjet-printed on rigid and flexible substrates. Red-emitting devices (λmax = 633 nm) exhibit, under ambient conditions, a maximum external quantum efficiency (EQEmax) of 1% with a related brightness of 30 cd/m2 at 10 mA/cm2.
