本文研究了钌基太阳能电池敏化剂Ru-II（LH_2）（2）（NCS）（2）（其中LH_2 = 2，2 ′-联吡啶-4，4 ′-二羧酸）的光伏稳定性。通过7000 h耐久性试验证明了其适用性，在试验结束时，未检测到明显的降解迹象。通过研究其在乙醇溶液中的光致和热致反应，解释了其显著的稳定性。还提出了关于如何避免可能对某些应用不期望的配体取代反应的建议。
The photovoltaic stability of Ru-II(LH2)(2)(NCS)(2) (where LH2 = 2,2'-bipyridyl-4,4'-dicarboxylic acid), a potential sensitizer for solar cells based on anatase, is examined. Its suitability for this role is demonstrated by a 7000 h endurance test, at the end of which no discernible signs of degradation can be detected. An explanation for its remarkable stability is provided by an investigation of its photo-and thermally induced reactions in alcoholic solution. Recommendations as to how to avoid ligand substitution reactions that may be undesirable for certain applications are also made.
