AI Technical Summary
In the existing technology, there are few non-fullerene acceptor materials for indoor photovoltaics, which is difficult to meet the needs of market applications. There is a need to develop new non-fullerene acceptor materials to improve the photoelectric performance of OPV devices.
A novel non-fullerene acceptor material and its mixture were designed. By optimizing the molecular structure, especially by limiting the alkyl chain configuration and electron-withdrawing ends of the compound, molecular stacking was reduced and charge transfer was achieved. The energy level was fine-tuned by modifying the branched side chains of appropriate lengths, making it suitable for photoactive layer materials.
It improves the photoelectric performance of organic photovoltaic cells, especially under indoor photovoltaic conditions, exhibiting excellent photoelectric conversion efficiency and charge separation effect.
