Co-sensitization technique has been appraised for attaining enhanced performance in dye-sensitized solar cells (DSSCs). DSSCs are fabricated with a heteroleptic Ru(II) sensitizer (RDAB1) containing 4,4’-diamino-2,2’-bipyridine (dabpy) ligand, co-sensitized with electron donor-acceptor type coumarin containing thiophene (CT) and indole (CI) moieties. The individual overall power conversion efficiency of the sensitizer is 5.44 %. Enhanced power conversion efficiencies of 6.34 % and 7.09 % were observed when RDAB1 was co-sensitized with Coumarin containing CI and CT respectively. The enhanced PCE can be attributed to the presence of co-sensitizers which effectively overcome the light absorption by I^-/I₃^-, dye aggregation and charge recombination.

共敏化技术已得到评估，可以在染料敏化太阳能电池（DSSC）中获得增强的性能。DSSC由含有4,4'-二氨基-2,2'-联吡啶（dabpy）配体的杂合Ru（II）敏化剂（RDAB1）制成，并与含有噻吩（CT）和吲哚的电子供体-受体香豆素共敏化。 （CI）部分。敏化剂的单个总功率转换效率为5.44％。当RDAB1与含CI和CT的香豆素共敏化时，观察到功率转换效率提高了6.34％和7.09％。增强的PCE可以归因于共敏化剂的存在下，通过I，其有效地克服了光吸收^- / I ₃ ^- ，染料聚集和电荷复合。
