报道了染料敏化太阳能电池（DSC）的两个关键研究课题：提高光伏性能和液体电解质的固化。提出了提高染料敏化太阳能电池光伏性能的方向。重点研究了TiO 2/染料与电解质层之间的界面，证明染料分子对TiO 2层的良好覆盖可以提高光伏性能。利用电子扩散系数和电子寿命对结果进行了讨论。另一个关键的研究项目是固化。液态电解质在不减少母体液体型DSC的情况下准固化，其中Grotthuss型机制被引入到固化的电解质中。正因为如此，电荷载体可以迅速移动，即使在硬粘土像电解质。
Two crucial research items on dye sensitized solar cells (DSC), increasing photovoltaic performances and solidification of liquid electrolytes, are reported. A direction to increasing photo-voltaic performances of DSCs is proposed. An interface between TiO2/dye and an electrolyte layer is focused on. It is proved that better coverage of TiO2 layers with dye molecules increases photovoltaic performances. The results are discussed by using electron diffusion coefficient and electron life time in TiO2 layers. Another crucial research item is solidification. Liquid electrolytes are quasi-solidified without decreasing the parent liquid type DSCs, where Grotthuss type mechanism are introduced to the solidified electrolytes. Because of this, charge carrier can move swiftly even in the hard clay like electrolytes.
