运用AFORS-HET软件对TCO/β-FeSi2(n)/a-Si(i)/c-Si(p)/μc-Si(p+)型太阳能电池各层结构之间的能带匹配进行了模拟。模拟结果表明，透明导电氧化膜与n型层间的能带匹配对太阳能电池的转化效率、开路电压和填充因子有较大影响，可以通过能带匹配有效地提高太阳能电池的转化效率。导带补偿会阻碍少数载流子的输运，界面态会加快少数载流子在界面的复合，降低导带失配，从而有利于提高太阳能电池的转化效率。衬底与背场的界面电场可以提高太阳能电池的转化效率。

The band matching among layers of a TCO/β-FeSi2(n)/a-Si(i)/c-Si(p)/μc-Si(p+) solar cell is simulated by using the software AFORS-HET. The simulation result shows that the matching of the transparent conductive oxide with the n-type layer has a greater influence on the conversion efficiency, open-circuit voltage and fill factor of a solar cell. The conversion efficiency of the solar cell can be improved effectively through band matching. Since conduction band compensation can hinter the transport of minority carriers and interface state can accelerate the recombination of minority carriers, conduction band mismatching can be reduced. This is beneficial to the improvement of the conversion efficiency of solar cells. The interface electric field between substrate and back field can improve the conversion efficiency of solar cells.
