Abstract
The photovoltaic stability of Ru-II(LH2)(2)(NCS)(2) (where LH2 = 2,2'- bipyridyl-4,4'-dicarboxylic acid), a potential sensitizer for solar ce lls based on anatase, is examined. Its suitability for this role is de monstrated by a 7000 h endurance test, at the end of which no discerni ble signs of degradation can be detected. An explanation for its remar kable stability is provided by an investigation of its photo-and therm ally induced reactions in alcoholic solution. Recommendations as to ho w to avoid ligand substitution reactions that may be undesirable for c ertain applications are also made.
