Abstract

A Ru(2,2′-bipyridine-4,4′-dicarboxylic acid)2(NCS)2 [RuL 2(NCS)2]/di-(3-aminopropyl)-viologen (DAPV)/tin oxide (SnO2) system was prepared and applied to extensive photocurrent generation with its maximum surface area. The SnO2 thin films on tin-doped indium oxide (ITO) were prepared using the chemical bath deposition method. Then, RuL2(NCS)2/DAPV on SnO2/ITO was easily prepared using self-assembled monolayers (SAMs). The photocurrent measurement of the system showed an excellent photocurrent of 20 nAcm -2 under the air mass 1.5 conditions (100mW cm-2), which was increased by a factor of four compared to ones without SnO2 layers.
