中文摘要： 固态染料敏化异质结太阳电池是近十年发展起来的新型光伏器件，它使用固态空穴传输材料替换液结染料敏化太阳电池中的电解液，可以有效解决电解液泄漏和腐蚀的问题。近年来，固态染料敏化异质结太阳电池的性能获得了明显进展，转换效率已接近液结染料敏化太阳电池的水平，显示了很好的应用潜力。但关于固态染料敏化异质结太阳电池的稳定性研究却严重滞后，只有很少的稳定性数据被报道，关于稳定性以及衰减机理的专门研究更少。太阳电池属于需要长期稳定工作的器件，其稳定性在整体性能中占有重要位置。因此，有必要对固态染料敏化异质结太阳电池的稳定性和衰减机理进行专门的系统研究，以了解其稳定性状况和控制稳定性的因素，并为进一步改善器件稳定性起指导作用。

英文摘要： Solid state dye-sensitized heterojunction solar cell is a new kind of photovoltaic devices developed in this decade. It uses solid state hole transporting materials instead of liquid electrolytes, which avoid the leakage and corrosion in liquid dye-sensitized solar cells. In recent years, the solar-to-electric efficiency of solid state dye-sensitized heterojunction solar cells has been remarkable improved, and the efficiencies of some best devices even close to that of liquid dye-sensitized solar cells. Although promising results have been gotten in device efficiency, few stability data were reported. Up to now, special study on device stability and decay mechanism was rare. Because solar cells are expected to continuous work for several years,the stability is one of the most important factors for solar cells. Therefore, it is necessary to take systematic studies on the device stability and decay mechanism for solid state dye-sensitized heterojunction solar cells. By this project, we can master the stability condition and the control factors in this kind of device, which will also provide necessary knowledge for further improving the device stability.
