Organic Sensitizers

New D-π-A configured organic sensitizers featuring halogen-substituted oxindole-bridged acceptor units have been synthesized for dye-sensitized solar cells applications. Among fluorine, bromine, and iodine substitution, the cell based on bromine incorporated dye exhibited the highest efficiency. The oxindoles in these sensitizers were found to assist the electron injection through the chelation of their amide carbonyl groups to the TiO2 surface. This study provides an alternate approach for future rational dye design to gain excellent DSSC performance.

Dual Functions

Oligomeric, hydrophobic coadsorbents based on polystyrene (Mn = 2400) terminated by a carboxylic acid exhibit dual functions in dye-sensitized solar cells: passivation of the TiO2 surface, and promotion of the strongly-anchored N719 dyes.
