The effect of anchoring group position and, in consequence, the orientation of the ruthenium dye molecule on titania surface on the performance of dye-sensitized solar cells has been studied intensively. Three model ruthenium sensitizing dyes bearing carboxylic anchoring group in ortho, meta or para position were synthesized and well characterized by spectroscopic, electrochemical, photophysical and photochemical measurements. The results were confronted with the quantum-mechanical calculations and discussed. The para derivative has been found as the most effective sensitizer with the cells efficiency twice higher than the meta and four times higher than the ortho derivatives.

深入研究了锚定基团位置以及二氧化钛表面上钌染料分子的取向对染料敏化太阳能电池性能的影响。合成了三种在邻位，间位或对位带有羧基锚定基团的钌型增感染料，并通过光谱，电化学，光物理和光化学测量对其进行了很好的表征。对结果进行了量子力学计算并进行了讨论。的对位衍生物已被发现为与细胞效率的最有效的敏化剂比两倍更高元和四倍比高邻衍生物。
