Abstract In this study, the impact of DC magnetic field on the power production, open-circuit voltage, photocurrent density and fill factor of a silicon photovoltaic (PV) cell/module is assessed. In this regard, the influence of DC magnetic field is first evaluated by presenting a novel theoretical electromagnetic force analysis formulating essential basis and concepts. Then, experimental measurements and data obtained from several tests conducted by arranging two different setups are given that verify theoretical results. In theory and practice, it is shown that depending on the direction of a DC magnetic field applied to a monocrystalline or polycrystalline silicon PV cell/module, different effects are observed. In detail, when the DC magnetic field points along the junction electric field of the silicon PV cell(s), i.e., the directions of the DC magnetic field and junction electric field are same or opposite, it has no effect on the parameters of the silicon PV cell/module. But, the power production, open-circuit voltage and photocurrent density of the silicon PV cell/module decrease when the DC magnetic field points in the other directions. Moreover, the reduction in the power production, open-circuit voltage and photocurrent density reaches its maximum when the DC magnetic field is applied in the direction perpendicular to the junction electric field. The above-mentioned points concluded in this paper are the contributions of this work to the state of the art of the topic.

磁场对硅基太阳能电池的影响

摘要 在这项研究中，评估了直流磁场对硅光伏 (PV) 电池/模块的发电量、开路电压、光电流密度和填充因子的影响。在这方面，首先通过提出一种新的理论电磁力分析来评估直流磁场的影响，该理论制定了基本的基础和概念。然后，给出了通过安排两种不同的设置进行的几次测试中获得的实验测量和数据，以验证理论结果。理论和实践表明，根据施加到单晶或多晶硅 PV 电池/模块的直流磁场的方向，观察到不同的效果。详细地，当直流磁场指向硅光伏电池的结电场时，即，直流磁场和结电场方向相同或相反，对硅光伏电池/组件的参数没有影响。但是，当直流磁场指向其他方向时，硅光伏电池/组件的发电量、开路电压和光电流密度会降低。此外，当在垂直于结电场的方向上施加直流磁场时，功率产生、开路电压和光电流密度的降低达到最大值。本文得出的上述要点是这项工作对本主题现有技术的贡献。当直流磁场指向其他方向时，硅光伏电池/组件的开路电压和光电流密度降低。此外，当在垂直于结电场的方向上施加直流磁场时，功率产生、开路电压和光电流密度的降低达到最大值。本文得出的上述要点是这项工作对本主题现有技术的贡献。当直流磁场指向其他方向时，硅光伏电池/组件的开路电压和光电流密度降低。此外，当在垂直于结电场的方向上施加直流磁场时，功率产生、开路电压和光电流密度的降低达到最大值。本文得出的上述要点是这项工作对本主题现有技术的贡献。
