and Ru6) have been synthesized, and their photophysical properties were investigated in solution and when adsorbed on the nanocrystalline TiO2 surface. The performance of Ru3 and Ru6 as charge transfer photosensitizers in nanocrytalline TiO2 based solar cells was also investigated. The best photovoltaic performance was obtained by the Ru3 based solar cell yielding a short circuit current of J sc =
已经合成了第一代和第二代树枝状大分子(Ru3和Ru6),并研究了它们在溶液中以及吸附在纳米TiO2表面上的光物理性质。还研究了Ru3和Ru6在纳米晶TiO2基太阳能电池中作为电荷转移光敏剂的性能。最佳的光伏性能是通过Ru3基太阳能电池获得的,短路电流为J sc = 5.52 mA.cm(-2),开路电压为V oc = 626 mV,对应于总转换效率eta = 1.80%,大约是参考化合物Ru1(eta = 0.91%)和第二代树状聚合物Ru6(eta = 0.95%)转化效率的两倍。第一代树状聚合物Ru3的特殊效率
