界面态对ZnO/AlSb太阳能电池性能影响的模拟研究

The Simulation of the Effect of Interface State on the ZnO/AlSb Solar Cell

运用AMPS软件对n-ZnO/i-AlSb/p-AlSb异质结太阳能电池的性能进行模拟,针对n/i异质结界面态对电池填充因子和转换效率的影响进行研究。结果表明,随着界面态密度增大,电池的填充因子和转换效率迅速下降,具体表现为界面态密度的增加促进光生载流子的复合从而电池并联电阻减小,最终导致电池的转换效率降低。

In this paper, the performance of the n-ZnO/i-AlSb/p-AlSb solar cell is simulated by AMPS（Analysis of microelectron- ie and photonic structures）. The effect of n/i interface state on the performance of the solar cell, such as fill factor FF and conversion efficiency η, was studied. It was shown that with the increase in interface state density, fill factor and conversion efficiency decreased rapidly, the mechanism of this change was investigated as well.
