研究目的
Investigating the efficiency of ternary organic solar cells by employing two compatible acceptors with similar LUMO levels.
研究成果
The study concludes that ternary OSCs with two compatible acceptors (IPTBO-4Cl and MF1) can achieve high PCE by optimizing the active layers. The similar LUMO levels of the two acceptors facilitate efficient electron transport, and the incorporation of MF1 as a morphology regulator improves the phase separation and molecular arrangement in the active layers.
研究不足
