| Research Abstract |
In this study, adsorption of dithiocarboxylic-acid-related molecules on an anatase TiO2surface has been studied by using X-ray photoelectron spectroscopy. After surface treatment with the molecules, we fabricated dye-sensitized solar cells (DSSC) and measured the performance of the cells. It was found that a sulfur atom in pyroridinedithiocarbamate (PDTC) or diethyldithiocarbamate (DEDTC) form bonding with oxygen atoms after attachment on a TiO2surface. After this surface treatment with PDTC or DEDTC, short circuit current (ISC) of DSSCs was highlyimproved. After the PDTC-treatment, photoconversion efficiency was increased 1.2 times.
