HETEROLEPTIC, DUAL TRIDENTATE RU(II) COMPLEXES AS SENSITIZERS FOR DYE-SENSITIZED SOLAR CELLS

摘要

Photosensitizers having a formula of RuL1L2 (1) are provided, wherein Ru is ruthenium; L1 and L2 are heterocyclic tridentate ligands. L1 has a formula of (2), and L2 has a formula of G1G2G3 (3), wherein G1 and G3 are selected from the group consisting of formulae (4) to (7), and G2 is selected from the group consisting of formulae (7) and (8). The above-mentioned photosensitizers are suitable to be used as sensitizers for fabrication of high efficiency dye-sensitized solar cells.
