用飞秒时间分辨的泵浦一探测方法对两种联吡啶-钌化合物[3，3’－（LL）]_2Ru(NCS)_2和[4，4’－（LL）]_2Ru（NCS）_2敏化体系的光吸收、电子注入（injection）及电子-空穴复合（recombination）动力学过程作了研究．提出了一个简单有效的计算模型，通过计算拟合得出两种敏化体系的电子注入均在50fs内完成。最后还对光电流谱作了研究，对影响光电转换效率（incidentphoton-to-currentef-ficiency(IPCE))的各种因素作了讨论.结果对太阳光的电能转换和太阳能电池的制作有一定的意义。
Two types of bipyridyl-ruthenium compounds [3,3 ’- (LL)] _2Ru (NCS) _2 and [4,4’ - (LL)] _2Ru (NCS) _2 were detected by a femtosecond time- Sensitization system of light absorption, electron injection (injection) and electron-hole recombination kinetics process was studied. A simple and effective calculation model is proposed. Through calculation and fitting, it is concluded that the electron injection of the two sensitization systems are completed within 50fs. Finally, the photocurrent spectra were also studied, and various factors affecting the conversion efficiency of photovoltaic (PVCE) were discussed.Results There is a certain degree of conversion of solar energy and solar cell production significance.
