Abstract

This paper reported the use of single-walled carbon nanotubes (SWCNTs) with terminal carboxylic acid groups as an electron-transfer bridge layer for improved photocurrent of viologen/Ru complex-based photoelectrochemical cells. The preparation of SWCNTs on tin-doped indium oxide (ITO) was prepared by spray-coating. The formation of Ru(2,2′-bipyridine-4,4′-dicarboxylic acid)₂(NCS)₂ [(RuL₂(NCS)₂)]/di(3- aminopropyl)viologen (DPAV)/SWCNTs/TTO was prepared by formation of acid-base complex. RuL₂(NCS)₂/DAPV/ITO and RUL₂(NCS) ₂/DAPV/SWCNTs/ITO showed photocurrents of 5.6 and 10.3 nA/cm ² under A.M 1.5 condition (I = 100 mW/cm²), respectively. The photocurrents of the RUL₂(NCS)₂/DAPV/SWCNTs/ITO cells in which Ru complexes were attached to carbon nanotubes by only acid-base complex formation were raised to 83.9% in comparison with RuL ₂(NCS)₂/DAPV/ITO due to retardation of recombination reaction in photoelectrochemical cells.
