Influence of the Wavelength on the Series and Shunt Resistances of a Polycrystalline Silicon Solar Cell n+-p-p+ in Frequency Modulation

Abstract

<p>A study of the illumination wavelength effect on the series and shunt resistances of a serial vertical junction silicon solar cell in frequency modulation is done. From the continuity equation of the minority carriers’ density, the expressions of the minority carriers’ density, the photocurrent density, and the photovoltage, are determined. The curves of the I-V characteristic permit us to deduce the series and shunt resistances, which depend on the wavelength and frequency modulation. A few values of series and shunt resistances in short and long wavelengths are determined respectively at the open circuit and the short circuit situation.</p>
