A computer simulation of the Earth's magnetic field in a period of normal polarity between reversals.

The scientists observed their static magnetic field prompted considerable variation in the panel's voltage and current parameters, fill factor, maximum power and conversion efficiency. The changes were produced by the 'Hall effect', which determines voltage differences across an electrical conductor.
This conclusion is drawn from the fact that magnetic field applied on a solar cell tends to deviate the electrons from their original paths. In addition to the deviation, magnetic field slows down the electrons approaching the cell junction leading to a reduction in the effective diffusion of the photo generated carriers.
