摘要：

This letter reports on the efficiency of In2S3/In2O3 photoelectrochemical cells by enhanced charge collection and reduced recombination reaction in the presence of single-walled carbon nanotubes (SWCNTs) on indium-doped tin oxide substrate. Nanocomposite system as In2S3/In2O3/SWCNTs was assembled using spray-coating and wet chemical processes. Due to enhanced charge collection and reduced recombination in the presence of SWCNTs, 52.9% increment of power conversion efficiency is achieved compared to those without SWCNTs layers.
