说明

K19 Dye 是一种两亲性钌敏化剂,具有良好的摩尔消光系数,在热应力和光照条件下仍保持稳定。它可以通过形成4,4'-双(对己氧基苯乙烯基)-2,2'-联吡啶、二氯(对甲基异丙基苯)钌(II)二聚体和4,4'-二羧酸的反应混合物来合成。 2,2'-联吡啶。它的总功率转换效率 (PCE) 为 11%,可用作电化学应用中的活性材料。

从 K-19 染料到二氧化钛导带的电子转移在 20 fs 内完成,而电荷复合的半衰期为 800 μs。这种敏化剂的高消光系数能够实现新一代薄膜染料敏化太阳能电池 (DSC),即使使用基于离子液体的粘性电解质,在全日光下也能产生高转换效率。或非挥发性溶剂,使太阳能电池器件在光照下表现出优异的稳定性。
K19 染料是一种有机金属染料,可用作制造染料敏化太阳能电池 (DSSC) 的光敏材料。它显示出 15.1 mA/cm2 的短路光电流密度、747 mV 的开路电压和 0.69 的填充因子。

一般描述

K19 Dye is an amphiphilic ruthenium sensitizer with a good molar extinction coefficient, which remains stable under thermal stress and light soaking. It can be synthesized by forming a reaction mixture of 4,4′-Bis(p-hexyloxystyryl)-2,2′-bipyridine, dichloro(p-cymene)ruthenium(II) dimer, and 4,4′-dicarboxylic acid-2,2′-bipyridine. It shows an overall power conversion efficiency (PCE) of 11% and can be used as an active material in electrochemical applications.
 

应用

Electron transfer from K-19 dye to the conduction band of Titania is completed within 20 fs while charge recombination has a half-life of 800 μs.  The high extinction coefficient of this sensitizer enable realization of a new generation thin-film dye-sensitized solar cells (DSCs) yielding high conversion efficiency at full sunlight, even with viscous electrolytes based on ionic liqs. or nonvolatile solvents, making solar cell devices exhibit excellent stability under light soaking.
K19 Dye is an organo-metallic dye that can be used as a photosensitizing material in the fabrication of dye sensitized solar cells (DSSCs). It shows a short circuit photocurrent density of 15.1 mA/cm2, an open circuit voltage of 747 mV and a fill factor of 0.69.
