摘要

温度和电极厚度是影响光伏电池性能的重要参数。基于文献中定义的扩散模型，利用MATLAB对这些效应进行了研究。该模型的主要特征是电子在半导体多孔膜(TiO2)中的扩散。因此，温度的升高对光电流的密度没有影响。随着厚度的增加，电流密度增大，但超过一定值(15µm)后电流密度减小。由于电池的内阻，厚度的增加导致功率和填充系数(FF)的降低。此外，功率转换效率(PCE)与温度和厚度成正比，但PCE从厚度的某一值(d = 5µm)开始下降。仿真结果表明，最佳电极厚度为5µm。

Effect of Temperature and Electrode Thickness on the Performance of Dye-Sensitized Solar Cells

The temperature and the electrode thickness are among the important parameters which affect the performance of photovoltaic cells. Based on a diffusion model defined in the literature, these effects have been investigated by using MATLAB. This model is mainly characterized by the diffusion of electrons in the semiconductor porous film (TiO2). As a result, the increase of temperature has no effect on the density of the photocurrent. Moreover, when the thickness increases, the current density increases but after a certain value (15 µm) it decreases. The increase of the thickness results to a decrease in power and fill factor (FF), due to the internal resistance of the cell. In addition, the power conversion efficiency (PCE) is proportional to the temperature, as well as the thickness, except that the PCE starts to decrease from a certain value of the thickness (d = 5 µm). The simulation shows that the optimal electrode thickness is 5 µm.
