Abstract
The present work is a theoretical study of the radial junction photovoltaic cell subjected to a magnetic field under monochromatic illumination. From a three-dimensional description, new analytical expressions of photocurrent density, photovoltage and electric power as a function of the magnetic field are established and by simulation on the Mathcad 15 software, we extracted the different curves. These representations allowed a thorough investigation of the operation of this model of a photovoltaic cell. It appears from this study that the amplitudes of parameters such as photocurrent density, photovoltage and electrical power are strongly attenuated when the photovoltaic cell is in the presence of a magnetic field assumed to be uniform over the entire region. For a magnetic field of 0.35 mT and a diffusion length, the short-circuit current decreased by 59.75% and the opencircuit photovoltage by 9.32%.
