Design and Synthesis of Narrow Bandgap Nonfullerene Acceptors for Low Energy Loss Near-Infrared Organic Solar Cells |
| 초록 |
Narrow bandgap organic semiconductors are relevant as key materials components for the fabrication of near-infrared (NIR) organic solar cells (OSCs) and organic photodetectors (OPDs). Much of the interest arises due to the tunability of their energy levels and absorption properties through designing the molecular architecture, especially for nonfullerene acceptors. However, the benefits of NIR organic semiconductors remain comparatively unexplored in the context of OSCs and OPDs. A critical challenge arises as one decreases optical bandgaps (Egopt) with respect to the counterbalance between the driving force for charge separation and voltage loss in the solar cell devices. The structure-property relationships in NIR nonfullerene solar cells and photodetectors were studied. |
