Aminated small molecule cathode interlayer for organic solar cells |
| 초록 |
It is essential that organic solar cells (OSCs) be able to show high efficiency and stability under sunlight before they are commercially accepted. From that point of view, research for cathode interlayers (CILs) has attracted attention in this field. The CILs as components of OSCs are very closely related to both efficiency and stability for the devices because it is in contact with photoactive organic materials. Herein, we propose a molecular design strategy for more efficient and stable OSCs. By modifying a small molecule bathocuproine with amine side-chains, which is used as a cathode interlayer in OSCs, the work function of cathodes was reduced so that the devices’ photovoltaic performance was slightly enhanced. In addition, the devices using modified bathocuproine CILs exhibited superior operational stability compared to the bathocuproine CILs. This work reveals the impact of amine side-chain in small molecule CILs on the photovoltaic performance and stability in OSCs. |
