A series of zinc phthalocyanine sensitizers (PcS6-18) having different adsorption sites have been designed and synthesized 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 sites affected the electron injection efficiency from the photo-excited dye into the nanocrystalline TiO2semiconductor as monitored by picosecond time-resolved fluorescence spectroscopy. The zinc phthalocyanine sensitizer PcS18possessing one carboxylic acid directly attached to the ZnPc ring and six 2,6-diisopropylphenoxy units showed a record PCE value of 5.9 % when used as a light-harvesting dye on a TiO2electrode under one sun condition.

已经设计和合成了一系列具有不同吸附位点的锌邻苯丙氨酸敏化剂（PCS6-18），以研究吸附位点结构对太阳能细胞性能在基于二苯胺的二苯胺染料染料敏感的太阳能细胞中的依赖性。吸附位点的变化影响了光启用染料的电子注入效率，该染料通过Picsecond Time-Time Coloded荧光光谱法监测到纳米晶Tio2Spemendoctor中。二苯胺敏化剂PCS18POSSS18羧酸直接连接到ZnPC环和六个2,6-二异丙基氧基单元显示，当在Tio2Electrode上用作tio2Electrode在一个太阳条件下时，将创纪录的PCE值为5.9％。
