In this study, the impact of DC electric and magnetic fields on the output power, open-circuit voltage, and photocurrent density of a silicon photovoltaic (PV) cell/module is assessed. In this regard, the influence of DC electric and magnetic fields is first evaluated in theory by formulating and discussing related basis and concepts. Then, experimental measurements and data obtained from two different sets of experiments are given that verify theoretical results. In theory and practice, it is shown that depending on the direction of a DC electric field applied to a silicon PV cell/module, it causes an increase or reduction in the output power and open-circuit voltage of the PV cell/module. In detail, when the DC electric field points in the direction of the junction electric field of the PV cell(s), the output power and open-circuit voltage of the silicon PV cell/module increase, otherwise the output power and open-circuit voltage decrease. Regarding the magnetic field, it is proved that depending on the direction of a DC magnetic field applied to a silicon PV cell/module, different effects are observed. In detail, when the DC magnetic field points along the junction electric field of the PV cell(s), it has no effect on the output power and open-circuit voltage of the silicon PV cell/module. But, the output power and open-circuit voltage of the silicon PV cell/module decrease when the DC magnetic field points in the other directions. Moreover, the reduction in the output power and open-circuit voltage reaches its peak when the DC magnetic field is applied in the direction perpendicular to the junction electric field.

直流电场和磁场对硅太阳能电池/组件的影响

在这项研究中,评估了直流电场和磁场对硅光伏(PV)电池/模块的输出功率,开路电压和光电流密度的影响。在这方面,首先在理论上通过阐述和讨论相关的基础和概念来评估直流电场和磁场的影响。然后,给出了从两组不同的实验中获得的实验测量结果和数据,以验证理论结果。从理论和实践上表明,根据施加到硅PV电池/模块的DC电场的方向,它会导致PV电池/模块的输出功率和开路电压增加或减少。详细地,当直流电场指向光伏电池的结电场方向时,硅光伏电池/模块的输出功率和开路电压增加,否则输出功率和开路电压降低。关于磁场,证明了取决于施加到硅PV电池/模块的DC磁场的方向,观察到不同的效果。详细地,当DC磁场沿着PV电池的结电场指向时,它对硅PV电池/模块的输出功率和开路电压没有影响。但是,当直流磁场指向其他方向时,硅光伏电池/模块的输出功率和开路电压会降低。而且,当在垂直于结电场的方向上施加DC磁场时,输出功率和开路电压的降低达到其峰值。
