PANCHROMATIC PHOTOSENSITIZERS AND DYE-SENSITIZED SOLAR CELL USING THE SAME

摘要

Panchromatic photo sensitizers having a Formula of ML₁L₂X were synthesized, wherein M represents ruthenium atom; X represents a monodentate anion; L₁ is heterocyclic bidentate ligand having one of formulae listed below:; wherein G₂ has one of formulae listed below: ; and L₂ is a tridentate ligand having a formula listed below: ; ;Substituents R₁, R₂, R₃ and R₄ of L₁ are the same or different and are selected from the group consisting of hydrogen, halogens, amino-group alkyl, alkoxy, alkylthio, alkylamino, halogenated alkyl, phenyl and substituted phenyl group. Substituents R₅, R₆ and R₇ of L₂ are the same or different and are selected from the group consisting of carboxylic acid and counter anion thereof, sulfonic acid and counter anion thereof, phosphoric acid and counter anion thereof. The above-mentioned photosensitizers are suitable to use as sensitizers for fabrication of high efficiency dye-sensitized solar cell.
