合成了一种高摩尔消光系数的杂配多吡啶钌敏化剂，其特征在于其辅助配体中的共轭富电子硒单元，并被证明是染料敏化太阳能电池中的有效敏化剂。用这种敏化剂染色的纳米晶二氧化钛膜显示出改善的光学吸收率，这对于具有薄光活性层的染料敏化太阳能电池是高度期望的。通过初步测试，该敏化剂已经在空气质量1.5的全球条件下实现了10.6%的高效率。
A high molar extinction coefficient heteroleptic polypyridyl ruthenium sensitizer, featuring a conjugated electron-rich selenophene unit in its ancillary ligand, has been synthesized and demonstrated as an efficient sensitizer in dye-sensitized solar cells. A nanocrystalline titania film stained with this sensitizer shows improved optical absorptivity, which is highly desirable for dye-sensitized solar cells with a thin photoactive layer. With preliminary testing, this sensitizer has already achieved a high efficiency of 10.6% measured under the air mass 1.5 global conditions.
