Near‐Infrared Absorbing Nonfullerene Acceptors for Organic Solar Cells

Materials with intense near-infrared (NIR) absorption, especially electron acceptors, play crucial roles in the development of organic solar cells (OSCs) due to their capability harvesting low-energy photons enable high photocurrent. Herein, NIR nonfullerene acceptors (NFAs) are focused by briefly reviewing understand molecular design strategies, structure–property–performance relationships, and great potential NFAs fabricating ternary tandem OSCs. Outlooks for future also provided considering material stability production cost based on current knowledges, hope aiding further field.
