sensitizers (PcS16–18) with different adsorption sites have been designed and synthesized in order to investigate the dependence of adsorption‐site structures on the solar‐cell performances in zinc–phthalocyanine based dye‐sensitized solar cells. The change of adsorption site affected the electron injection efficiency from the photoexcited dye into the nanocrystalline TiO2 semiconductor, as monitored by
一系列锌酞菁敏化剂(的PcS16 - 18)具有不同的吸附位点已经被设计和为了研究吸附现场结构对锌-酞菁染料敏化太阳能电池的太阳能电池性能的依赖性合成。皮秒时间分辨荧光光谱法监测到,吸附位点的变化影响了从光激发染料到纳米晶TiO 2半导体中的电子注入效率。锌-酞菁敏化剂PcS18具有一种直接与ZnPc环相连的羧酸和六个2,6-二异丙基苯氧基单元,当用作TiO2上的光吸收染料时,其功率转换效率值达到了创纪录的5.9%。2个电极在一种模拟太阳条件下工作。
