Study of the Series Resistance of a Solar Cell Silicon under Magnetic Field from of Junction Surface recombination Velocity of Minority Charge Carriers at the junction limiting the open circuit (Sfoc)

The open circuit is a operation point the solar cell corresponding to a maximum photovoltage and a almost nul photocurrent. The phenomenological parameter that sets this operating point of the solar cell is the junction recombination velocity of minority charge carriers at the junction. The open circuit is set when the recombination rate is low. In this article, we consider an operation point near the open circuit of solar cell, that is to say the one that limits the operation of the solar cell open circuit and its study versus to an external magnetic field is proposed. This study allowed the determination of the series resistance of the solar cell according to the external magnetic field. Thus, expression of the minority charge carrier density is determined from the continuity equation and studied for different values of the magnetic field. From this study, the open circuit voltage (Voc) and the junction surface recombination velocity limiting the open circuit (Sfoc) are determined and studied for different values of magnetic field. The determination of the series resistance is proposed from the curve of series resistance versus of the solar cell operation point by considering Sfoc
