Spin Dynamics Study of Next Generation Solar Energy"Rare-Earth Dye-Sensitized Solar Cells"

在稳态ESR谱中，准确地揭示了稀土染料分子的复自旋态。在此基础上，阐明了稀土染料分子具有较长的驰豫时间，这表明它们具有较高的光电转换效率。这些材料的少量样品阻碍了我们研究染料敏化太阳能电池的机理。然而，我们成功地用时间分辨ESR波谱阐明了有机光导的机理。

In the steady state ESR spectroscopy, the complex spin-state of the rare-earth dye molecules was revealed exactly. Then, it was clarify that these molecules are possible to indicate the high photoelectronic conversion efficiency, due to the long relaxation time in the rare-earth dye molecules. A little sample amount of these materials prevent us to examine the mechanism of dye sensitized solar cell. However, we were successful to clarify the organic photoconductive mechanism by using time-resolved ESR spectroscopy.
