In order to improve performance of organic optoelectronic devices, such as polymer light emitting diodes (OLEDs) and polymer solar cells (OSCs), modification of the interface between the electrode and the organic active layer is regarded as important issue. A hole transport layer (HTL) is required to reduce energy barrier between the anode and the organic active layer to improve transportation of holes. In this study, we synthesized three conjugated polyelectrolytes (CPEs) with different conjugation length and they were introduced as HTL of PLEDs and PSCs. The change of energy level and device performances with different dipole moment of CPEs was investigated. |
