[OLEDp2-6L] The Influence of Bottom Layer on the Performance of Perovskite LEDs

*Jungwon Kim1, Min Chul Suh1 (1. Kyung Hee University (Korea))

Keywords:perovskite light-emitting diode, interlayer, precursor

We found the interface mixing could be occurred when a hydrophilic interlayer is utilized. To solve this problem we tried to change the perovskite precursor materials to exclude interlayer. As a result, we found that we could skip the interlayer by changing a composition of perovskite.
