Two novel ruthenium complexes, MR-1 and MR-2 were synthesized for use in dye-sensitized solar cells (DSSCs). Under similar fabrication conditions, the photovoltaic performances of these dyes were evaluated and compared to the standard ruthenium complex N719. MR-1 and MR-2 showed the efficiencies of 8.19% and 5.32%, respectively, while N719 achieved 7.66%. MR-1 also displayed higher V_OC than MR-2, which is due to the larger molecular size and higher molar extinction coefficient of the former, which translates into less dye aggregation on a thinner film of TiO₂. Incorporation of terthiophene as a linker reduces the band gap of MR-1 when compared to that of MR-2. The influence of π-conjugated bridge on optical and electrochemical properties was investigated. Results demonstrated that the absorption band of MR-1 displayed higher extinction coefficient with a broader absorption compared to MR-2 and the benchmark Ru(II) dye, N719, due to the enhancement of electron donating ability of π-conjugated bridge.

合成了两种新型钌配合物MR-1和MR-2，用于染料敏化太阳能电池（DSSC）。在相似的制造条件下，评估了这些染料的光电性能，并将其与标准钌配合物N719进行了比较。MR-1和MR-2的效率分别为8.19％和5.32％，而N719的效率为7.66％。MR-1也显示更高的V _OC比MR-2，这是由于较大的分子大小和前者的较高的摩尔消光系数，这转化为较少染料聚集在TiO的较薄薄膜₂。与MR-2相比，并入对噻吩作为连接基可减少MR-1的带隙。研究了π共轭桥对光学和电化学性能的影响。结果表明，与MR-2和基准Ru（II）染料N719相比，MR-1的吸收带具有更高的消光系数和更宽的吸收率，这归因于π共轭桥的给电子能力的增强。
