利用电化学阻抗谱分析了老化和循环变化的温度对染料太阳能电池电参数的影响。由于薄膜中电子传输电阻的增加，光电极总电阻随时间而增加。另一方面，与温度处理前相比，温度处理后的光电极复合电阻通常更大，膜中的电子寿命更长，并且对电极上的电荷转移电阻更小。与参考电池相比，这些效应与经过温度处理的电池的劣化速度较慢相关。
Effects of aging and cyclically varying temperature on the electrical parameters of dye solar cells were analyzed with electrochemical impedance spectroscopy. Photoelectrode total resistance increased as a function of time due to increasing electron transport resistance in the film. On the other hand, photoelectrode recombination resistance was generally larger, electron lifetimes in the were film longer, and charge transfer resistance on the counter electrode was smaller after the temperature treatments than before them. These effects correlated with the slower deterioration rate of the temperature-treated cells, in comparison to the reference cells.
