摘要：

A dye-sensitized solar cell (DSC) was fabricated using a new beta-diketonato ruthenium(II) sensitizer with a broad absorption range and a high molar extinction coefficient of 11.3 x 10(3) M-1 cm(-1) at 584 nm. Efficient sensitization of nanocrystalline TiO2 film was observed across the whole visible range and into the near-IR region as far as 1000 nm. The incident photon-to-current conversion efficiency (IPCE) spectrum was consistent with the absorption spectrum and resulted in a high short-circuit photocurrent density (J(sc)) of 19 mA cm(-2).
