Influence of Ancillary Ligands in Dye-Sensitized Solar Cells

A review. Dye-sensitized solar cells (DSSCs) have motivated many researchers to develop various sensitizers with tailored properties involving anchoring and ancillary ligands. Ancillary ligands carry favorable light-harvesting abilities and are therefore crucial in detg. the overall power conversion efficiencies. The use of ancillary ligands having aliph. chains and/or π-extended arom. units decreases charge recombination and permits the collection of a large fraction of sunlight. This review aims to provide insight into the relationship between ancillary ligand structure and DSSC properti...
