The exploration of high-performance and low-cost wide-bandgap polymer donors remains critical to achieve high-efficiency non-fullerene organic solar cells (OSCs) beyond current thresholds. Herein, the 1,2,3-benzothiadiazole (iBT), which is an isomer of 2,1,3-benzothiadiazole (BT), is used to design wide-bandgap polymer donor PiBT.
