Oligo(aniline)-based Hole Transport Layer for Organic Solar Cells |
| 초록 |
The contribution of interfacial layers to device performance and stability is considered important. The most widely used hole transport layer (HTL) for conventional organic solar cells (OSCs) – PEDOT:PSS has some shortcomings such as the acidity and the hygroscopicity which cause the limitation for long-term stability. In this study, we report the doping system of an aniline derivative (PTA) and an aryl sulfonic acid (NSO-2), which can be employed as HTL for OSCs. Devices fabricated from this HTL on PM6:Y6 active layers exhibited comparative power conversion efficiency (PCE) with control device of PEDOT:PSS (14.94% vs. 15.05%). Moreover, the devices with PTA:NSO-2 HTL also emphasizes its better moisture stability than PEDOT:PSS. Therefore, this initial result demonstrates the potential of aniline-based materials as HTL for OSCs as well as motivates the further optimization to achieve the higher photovoltaic performance. |
