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.

第一个基于噻吩并[3,4- b ]吡嗪的具有线性A ₂ –A ₁ –D–A ₁ –A ₂骨架的小分子受体，用于高V _oc为1.05 V的无富勒烯有机太阳能电池†

合成了第一个基于噻吩并[3,4- b ]吡嗪（TP）的非富勒烯受体，并将其命名为TP21，它显示出1.65 eV的窄带隙和-3.61 eV的高LUMO。基于J61：TP21的有机太阳能电池在1.05 V的高开路电压（V _oc）下实现了5.81％的中等功率转换效率（PCE）。
