Abstract

A Ru(2,2′-bipyridine-4,4′-dicarboxylic acid)₂(NCS)₂ [RuL₂(NCS)₂]/di-(3-aminopropyl)-viologen (DAPV)/In₂O₃ nanorod system was prepared and applied for photocurrent generation with its maximum surface area . The In₂O₃ nanorods were prepared using the chemical-bath-deposition method. The various surface morphology of In₂O₃ were obtained by adding different amounts of 0.1 M HCl solution to the indium-containing solution. The DAPV and RuL₂(NCS)₂ were easily self-assembled on the indium-oxide surface. The energy levels of RuL₂(NCS)₂, DAPV, In₂O₃, and tin-doped indium oxide (ITO) were well arranged, and the system forms an efficient acceptor-sensitizer. The photocurrent measurement of the systems showed excellent photocurrent of 50 nA/cm² under the air mass (AM) 1.5 condition (100 mW/cm²), which was increased by a factor of ten compared to ones without indium-oxide layers.
