Synthesis of novel beta-diketonate bis(bipyridyl) Os(II) dyes for utilization of infrared light in dye-sensitized solar cells.
Bis(bipyridyl) osmium(II) dyes having a beta-diketonate ligand were synthesized in order to utilize visible and infrared light for dye-sensitized solar cells. Compared to black dye, under AM 1.5 irradiation (100 mW cm(-2)), DSCs using our novel Os dyes exhibited a better spectral response in the near-IR region (by 1050 nm) and showed a higher J(SC) value of 23.7 mA cm(-2).
