Capacitance Voltage Characterization of Bifacial Silicon Solar Cell Under Polychromatic Modulated Illumination

The aim of this work is to present a theorical study of a capacitance voltage characterizationof a bifacial silicon solar cell under polychromatic modulated illumination. From the excess minoritycarrier’s density in the solar cell, the photocurrent density and the photovoltage are derived. The diffusioncapacitance was measured with both as a function of voltage and the junction surface recombinationvelocity. Electric polarization effects are shown through different C-V plots. For all the studied parameters,we exhibited the effect of electric feld parameters on the capacitance voltage characterization and theoperating point of the cell through the junction recombination velocity.
