摘要：
The first thieno[3,4-b]pyrazine (TP) based non-fullerene acceptor was synthesized and named as TP21, which shows a narrow band gap of 1.65 eV and a high-lying LUMO of -3.61 eV. Organic solar cells based on J61:TP21 realized a moderate power conversion efficiency (PCE) of 5.81% with a high open-circuit voltage (V-oc) of 1.05 V.
