摘要
A Ru(2,2'-bipriding-4,4'-dicarboxylic acid(2)(NCS)(2) [RuL2(NCS)(2)]/di-(3-aminoprophyl)-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 systems forms an efficient acceptor-sensitizer. The photocurrent measurement of the systems showed exellent photocurrent of 50 nA/cm(2) under the air mass (AM) 1.5 condition (100 mW/cm(2)), which was increased by a factor of ten compared to ones without indium-oxide layers.
