| 摘 要： | 考虑到nip型ITO/a-Si(n)/a-Si(i)/a-Si(p)/Al]非晶硅光伏电池的各膜层厚度、掺杂浓度等因素,对非晶硅光伏电池的转换效率、填充因子、开路电压等性能参数进行了数值分析与讨论。结果表明,随p型层厚度的增加,光伏电池的短路电流密度、转换效率、开路电压值都有所增加。当本征层的厚度增加时,短波段内的光谱响应变差、内量子效率下降。当n型层厚度为5 nm,本征层厚度为5 nm,p型层厚度为10μm,受主掺杂浓度为2.5×1019cm-3,施主掺杂浓度为1.5×1016cm-3时,转换效率可达9.728%。

| Abstract: | Taking into account the film layer thickness and silicon impurities of amorphous silicon solar cells with the nip-typeITO/a-Si(n)/a-Si(i)/ a-Si(p)/Al] structure,the conversion efficiency,fill factor,and open circuit voltage of the nip-type amorphous silicon solar cell are numerically analyzed and discussed.The results show that the short circuit voltage,conversion efficiency,and open circuit voltage increase as the thickness of p-type layer increases.With the increase in the thickness of intrinsic layer,th... |
