Highly Efficient Polymer-Based Light-Emitting Diodes and Solar Cells Using PEDOT:GO Composite as a Hole Transport Layer |
| 초록 |
We demonstrate highly efficient PLEDs as well as PSCs using a solution-processable PEDOT:PSS:graphene oxide (GO) (PEDOT:GO) composite layer as hole transport layers (HTLs). It decreases remarkably exciton quenching and suppresses bimolecular recombinations between the PEDOT:GO composite layer and the active layer, and increases the recombinations of holes and electrons within the active layer by the blocking behavior of the electrons from a fluorescent semiconductor because of the existence of GO with large bandgap (~3.6 eV) in the PEDOT:GO composite layer, therefore leading to an enhancement of device efficiency in PLEDs and PSCs. The optimized PSCs and PLEDs with a PEDOT:GO composite HTL layer shows the power conversion efficiency of 8.21 % for PSCs as well as the maximum luminous efficiency of 21.74 cd/A (at 6.4 V) for PLEDs, which were improved by approximately 120 and 220 %, respectively, compared to reference PLEDs and PSCs with PEDOT:PSS layer. |
