摘　　要：通过分析偏压条件下染料敏化太阳电池的电流电压特性,给出遮挡情况下染料敏化太阳电池组件的电学模型。模拟分析部分遮挡情况下,染料敏化太阳电池组件的输出特性和功率损失,以及反向导通时染料敏化太阳电池的负载特性。结果表明:部分遮挡情况下并联组件中被遮挡电池处于正偏压下,由于难以被击穿,能耗极小。串联组件中被遮挡电池易工作在负偏压区域而成为耗能负载,但作为负载的功率较低。A numerical model of I- V characteristics of partial shaded module is presented by analyzing the numerical model for dye-sensitized solar cell under forward and reverse bias potential. The power loss and the output performance of dye-sensitized solar cell module under partial shading condition are investigated. The hot spot effect of dye-sensitized solar cell under indoor condition is experimentally studied. The results indicate that the threshold voltage of dyesensitized solar cell is very low in reverse bias. Shaded individual cells in parallel module have little effect on normal ones, while individual cells under shading condition in series module can easily operate in the reverse bias region and induce power consumption, but the power dissipated in these cells which working under reverse bias is very small, the effect of hot spot is not obvious.
