硅垂直多结（VMJ）太阳电池具有成本低、串联电阻小等优点，在聚光光伏方面具有很好的应用前景。然而，很少有讨论硅VMJ电池在非均匀照明下的热和电性能。本文首先采用有限元法计算了硅VMJ电池在500个太阳的一维非均匀光照下的热性能，然后在此基础上利用SPICE软件计算了电池的电学性能。结果表明，当水槽与细胞面积比为500倍时，细胞平均温度随光照不均匀程度的增加而增加，当水槽与细胞面积比为2500倍时，细胞平均温度变化不大。当面积比为500倍时，电池的效率不随非均匀光照度的增加而降低，当面积比为2500倍时，电池的效率随非均匀光照度的增加而增加。因此，硅VMJ电池在500太阳的一维非均匀照射下具有比硅平面结电池更好的性能。
The silicon vertical multi-junction (VMJ) solar cell has low costs and low series resistance, thus it has a good potential in concentration photovoltaics. However, there were few discussions about the thermal and electrical performance of silicon VMJ cell under non-uniform illumination. In this work, the thermal performance of silicon VMJ cell under 1D non-uniform illumination of 500 suns was calculated using finite element method first, and then the electrical performance of the cell was calculated using SPICE software based on the thermal simulation results. It was found that the mean temperature of the cell increased with the degree of non-uniform illumination when the area ratio of the sink to the cell was 500X, and the mean temperature changed few when the area ratio was 2500X. The efficiency of the cell did not decrease with the increase of the degree of non-uniform illumination when the area ratio was 500X, and the efficiency increased with the degree of non-uniform illumination when the area ratio was 2500X. Thus, the silicon VMJ cell had better performance than silicon planar junction cell under 1D non-uniform illumination of 500 suns.
