Abstract:
Herein, we demonstrated a polarized thin film (PBzP2C4) electrochemically deposited from phosphonate and a carbazole-difunctionalized conjugated molecule as an aluminum-doped zinc oxide (AZO) modifier for high-performance inverted organic solar cells (OSCs)/polymer light-emitting diodes (PLEDs). The PBzP2C4 film showed a controllable thickness and fully covered the surface of AZO, resulting in a smooth and uniform electrode. PBzP2C4 modification reduced the WF of AZO and highly improved the electron extraction/injection in inverted OSCs/PLEDs. As a result, a maximum power conversion efficiency of 10.35% was achieved for inverted OSCs with PTB7-Th:PC71BM as the active layer, and a maximum luminous efficiency of 21.4 cd A-1 was obtained for inverted PLEDs based on P-PPV.
