The modification of the interface between the electrodes and the organic active layer of organic optoelectronic devices, such as polymer light emitting diodes (OLEDs) and polymer solar cells (PSCs), is regarded as important issue In order to improve performance. A hole transporting layer (HTL) play a role 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 to control dipole moment. The PLEDs and PSCs were fabricated by using CPEs as HTL. The device performances with different dipole moment of CPEs were enhanced, compared with PEDOT:PSS based device. |
