A ruthenium sensitizer with an extended π-conjugated terpyridine (TUS-42) has been synthesized for dye-sensitized solar cells (DSCs). Upon extension of the π-conjugated system of the terpyridine ligand, the conversion efficiency of the DSC with TUS-42 improved successfully to 10.7%, which is almost comparable to that of one of the most efficient ruthenium sensitizers (Black dye). Interestingly, an extremely large short-circuit current density (Jsc) value (22.7 mA/cm(2)) was obtained in the DSC with TUS-42 even though the amount of dye adsorption to the TiO2 photoelectrode is relatively small.
一种带有扩展π共轭三联吡啶的钌敏化剂（TUS-42）已被合成用于染料敏化太阳能电池（DSC）。随着三联吡啶配体π共轭体系的扩展，含有TUS-42的DSC的转换效率成功提高到了10.7%，这几乎与最有效的钌敏化剂之一（黑色染料）相当。有趣的是，在含有TUS-42的DSC中，即使染料在TiO2光电极上的吸附量相对较小，也获得了极大的短路电流密度（Jsc）值（22.7 mA/cm²）。
