Passivated perovsikite light-emitting diodes and preparation method thereof |
| abstract |
The present invention relates to a perovskite type light emitting diode comprising an amine-based passivation agent on a perovskite layer, wherein ethylenediamine (EDA) as an amine-based passivation agent penetrates deeply into the surface of the perovskite and crystals It has been confirmed that the device stability of the perovskite is effectively improved by effectively passivating the defective portion of the perovskite, the flashing phenomenon of the photoluminescence (PL) is completely suppressed, and the photoluminescence efficiency is improved, The perovskite passivated by the passivation treatment can be used as an excellent light emitting device. |
