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.

在这项研究中，使用X射线光电子光谱学研究了二硫代二羧酸二邻二羧联相关的分子的吸附。用分子进行表面处理后，我们制造了染料敏化的太阳能电池（DSSC），并测量了细胞的性能。已经发现，在tio2surface上附着后，在吡啶式硫代硫代氨酸（PDTC）或二硫代二硫代氨酸二硫代氨基酯（DEDTC）中形成氧原子的硫原子。用PDTC或DEDTC进行表面处理后，DSSC的短回路电流（ISC）得到了高度改善。 PDTC处理后，光转换效率提高了1.2倍。
