Abstract

We have developed a new β-diketonato Ru(II) complex, Ru(4,4′,4″-tricarboxy-2,2′:6′,2″-terpyridine) [4,4,4-trifluoro-1-(4-fluorophenyl)butane-1,3-dionato](NCS)[(C<SUB>4</SUB>H<SUB>9</SUB>)<SUB>4</SUB>N]<SUB>2</SUB> (<B>1</B>) which shows very efficient panchromatic sensitization of nanocrystalline TiO<SUB>2</SUB> solar cell over the whole visible range extending into the near IR region (ca. 950 nm). A solar energy conversion efficiency of 8.9% was attained under standard AM 1.5 irradiation (100 mW cm<SUP>−2</SUP>) with a short-circuit photocurrent density of 20.4 mA cm<SUP>−2</SUP>, an open-circuit photovoltage of 0.65 V, and a fill factor of 0.67.
