研究目的
Investigating the performance of an A–D–D–A-type near-infrared non-fullerene small-molecule acceptor IDT2-DFIC in polymer solar cells compared to A–D–A-type small-molecule acceptor IDIC-4F.
研究成果
The A–D–D–A-type NIR NF-SMA IDT2-DFIC exhibits superior performance in polymer solar cells compared to IDIC-4F, with a higher PCE of 10.06% and lower energy loss. This suggests an efficient molecular design strategy for constructing NF-SMAs with NIR absorption.
