Searching the cost‐effective organic semiconductors is strongly needed in order to facilitate the practice of organic solar cells (OSCs), yet to be fulfilled. Herein, we have succeeded in developing two non‐fused ring electron acceptors (NFREAs), leading to the highest efficiency of 16.2 % for the N...
