铝背场对单晶硅太阳电池输出特性的影响

Influence of Al-BSF on Electrical Properties of Monocrystalline Silicon Solar Cells

利用PC1D软件模拟了n+/p-p+结构的单晶硅太阳电池铝背场与硅片厚度对其输出特性的影响。结果表明,有铝背场时太阳电池获得明显的开路电压、短路电流以及光电转换效率的增益;硅片厚度越小,铝背场对其输出特性的影响越大;在有铝背场情况下,硅片厚度为120μm时,可获得最大的光电转换效率。

The PC1D was used to simulate the influence of Al-BSF and wafer thickness on electrical properties of n^＋/p-p^＋ structural monocrystalline silicon solar cells. It is found that solar cells with the Al-BSF structure can gain obvious open circuit voltage, short-circuit current, as well as photoelectric conversion efficiency; the smaller the wafer thickness is, the bigger of the effect of Al BSF works on the electrical properties; when the wafer thickness is 120 m, the solar cells can get the biggest photoelectric conversion efficiency.
