摘　　要：某些基体材料杂质对太阳电池的转换效率有显著的消极影响,磁场可以使杂质原子能级分裂,改变杂质原子的能级位置,借助磁场可以减小杂质元素对太阳电池转换效率带来的消极影响。以杂质元素锰为例,定量计算了磁场对该杂质元素能级分裂作用,并定性分析了这种能级分裂对太阳电池转换效率的影响。Several impurities have significantly negative influence on conversion efficiency of solar cells. Magnetic fields can bring about energy level splitting of the atoms of impurities to change the energy level. Taking the example of impurities Mn, the energy level splitting of the atom of Mn in magnetic fields was computed, and influence on conversion efficiency of solar cells which was exerted by this level splitting was discussed.
