In the paper, the quinoxaline(QX) polymer donor material with 4-methoxythiophene as the side chain was designed and synthesized by side chain modification engineering and named as PBMOQX. It has good solubility in common organic solvents. In addition, a series of characterizations of the conjugated polymer were performed. There is a good spectral absorption at 300–700 nm with an electrochemical bandgap of 1.83 eV and an optical bandgap of 1.63 eV. With 0.5% of 1, 8-diiodooctane as an additive in a mixing ratio of PBMOQX: PC₇₁BM = 1:1.5, the device achieves a power conversion efficiencies (PCE) of 6.94%. These studies indicate that the novel copolymer PBMOQX is a promising photovoltaic donor material for high efficiency polymer solar cells (PSCs).

本文通过侧链修饰工程设计合成了以4-甲氧基噻吩为侧链的喹喔啉（QX）聚合物供体材料，命名为PBMOQX。在普通有机溶剂中具有良好的溶解性。另外，对共轭聚合物进行了一系列表征。在300-700 nm处有良好的光谱吸收，电化学带隙为1.83 eV，光学带隙为1.63 eV。在PBMOQX：PC ₇₁ BM = 1：1.5的混合比下，以0.5％的1，8-二碘辛烷作为添加剂，该器件的功率转换效率（PCE）为6.94％。这些研究表明，新型共聚物PBMOQX是用于高效聚合物太阳能电池（PSC）的有前途的光伏供体材料。
