Asymmetrically Trifluoromethylated Non-fused Electron Acceptor for High-Efficiency and Stable Organic Solar Cells
{{output}}
Fused-ring electron acceptors (FREAs) have advanced significantly in organic solar cells (OSCs) but suffer from complex synthesis and high production costs. As a cost-effective alternative, nonfused-ring electron acceptors (NFREAs) offer structural simplicity ... ...
