Abstract The performance of dye-sensitized solar cells (DSSCs) can be influenced by the sensitizer. Therefore, three heteroleptic ruthenium complexes, cis-[Ru(dcbpy)(bpy)(NCS)2] (Ru-bpy), cis-[Ru(dcbpy)(dppz)(NCS)2] (Ru-dppz) and cis-[Ru(dcbpy)(dppx)(NCS)2] (Ru-dppx) (dcbpy = 4,4′-dicarboxylic-2,2′-bipyridine, NCS = isothiocyanate) sensitizers, were synthesized using one pot synthesis. The structures and functionalization of the ligands in each complex sensitizer were confirmed using FT-IR and NMR analyses. They were then systematically studied to determine their light absorption spectrum, the metal-centered oxidation peak, and electron recombination properties using a UV–vis spectrophotometer and electroanalytical techniques (i.e., CV, EIS, and LSV). The criteria for an efficient DSSC ruthenium sensitizer were drawn based on the structure-property relationship. It was found that the power conversion efficiency (ɳ) of the sensitizers were in the sequence of Ru-dppz (ɳ = 0.40%)

摘要 染料敏化太阳能电池（DSSCs）的性能会受到敏化剂的影响。因此，三种杂配钌配合物，顺式-[Ru(dcbpy)(bpy)(NCS)2] (Ru-bpy)、顺式-[Ru(dcbpy)(dppz)(NCS)2] (Ru-dppz) 和顺式-[Ru(dcbpy)(dppx)(NCS)2] (Ru-dppx)（dcbpy = 4,4'-二羧酸-2,2'-联吡啶，NCS = 异硫氰酸酯）敏化剂，使用一锅法合成。使用 FT-IR 和 NMR 分析确认了每个复合敏化剂中配体的结构和功能化。然后使用紫外-可见分光光度计和电分析技术（即 CV、EIS 和 LSV）系统地研究它们以确定它们的光吸收光谱、以金属为中心的氧化峰和电子复合特性。高效 DSSC 钌敏化剂的标准是基于结构-性能关系得出的。发现敏化剂的功率转换效率（ɳ）按Ru-dppz（ɳ=0.40%）的顺序排列
