中文摘要：

根据染料敏化太阳能电池（DSSC）的等效电路,应用MATLAB/Simulink工具建立仿真模型,对DSSC的输出伏安特性及输出功率进行仿真,讨论串联电阻和分流电阻对DSSC性能的影响。仿真结果表明,随着串联电阻的增加,开路电压不变,短路电流密度、最大输出功率及填充因子降低;随着分流电阻的增加,开路电压、短路电流密度、最大输出功率及填充因子均升高,但是数值增加越来越慢。通过仿真结果来指导实验：减小电池基底的阻值,使材料之间紧密接触,串联电阻的阻值就会越小,得到DSSC的性能就越好;还可以通过在基底镀上一层致密膜,增加分流电阻的阻值,提高DSSC的性能。仿真结果可以作为优化DSSC结构的理论依据。

英文摘要：

According to the equivalent circuit of dye-sensitized solar cells（DSSC）,a simulation model was built up using MATLAB/Simulink tool,which was used to simulate the output characteristics and output power of DSSC.The effect of series resistance and parallel resistance on the performance of DSSC was investigated.The results indicated that the density of short-circuit current,the maximum output power and the fill factor were decreased with increasing series resistance,whereas the open-circuit voltage,the density of short-circuit,the maximum output power and the fill factor was increased with increasing parallel resistance,and quantitative value increased slower.Such results can be used to direct experiments.By reducing resistance of battery and contacting the materials closely,the value of series resistance would be decreased and the properties of DSSC would become more better.The value of parallel resistance would be increased by coating dense membrane on the substrate,and the performance of DSSC would also be better.
