Water-stable polymer hole transport layer inorganic and perovskite light-emitting diodes |
| 초록 |
Poly(3,4-ethylenedioxythiophene):poly-styrenesulfonate (PEDOT:PSS) is commonly used as a hole-transport material inoptoelectronic devices such as organic and perovskite-based solar cells andlight-emitting diodes. Moreover, PEDOT:PSS is suitable for fabricating flexibleand roll-to-roll devices by solution processing. However, PEDOT:PSS hashygroscopic properties, and the water molecules it attracts can damage theactive layer of devices, leading to reduced device stability. In this study, wedevelop a water-stable hole transport layer (HTL) in perovskite light-emittingdiodes (PeLEDs) and organic light-emitting diodes (OLEDs) via a simple andeffective method, which involves the modification of PEDOT:PSS with2-pentacosa-10,12-diynamidoethylsulfate as a photo-crosslinking agent. Experimentalresults show that devices with the developed HTL show greater long-termstability than PeLEDs and OLEDs based on pristine PEDOT:PSS. |
