An Approach To Extract The Parameters Of Solar Cells From Their Illuminated I-V Curves Using The Lambert W Function, Ahmed A. El Tayyan
An Approach To Extract The Parameters Of Solar Cells From Their Illuminated I-V Curves Using The Lambert W Function, Ahmed A. El Tayyan
Turkish Journal of Physics
In this article an approach based on the Lambert W function is applied to analysis of various types solar cells and solar modules at a given insolation level and temperature; it can be used to extract accurate values of the parameters of a solar cell/module using experimental data or information available from the datasheet. These parameters are the photocurrent I_{ph}, the reverse saturation current I_o, the diode ideality factor a, the series resistance R_s, and the shunt resistance R_{sh}. The parameters I_o, a, R_s, and R_{sh} are calculated with the aid of 4 equations that can be solved simultaneously while …

On The Capacitance Of Crystalline Silicon Solar Cells In Steady State, Fabe Idrissa Barro, Moustapha Sane, Bernard Zouma
Turkish Journal of Physics
In this work, an analytical approach is presented for modeling the capacitance of crystalline silicon solar cells. Based on a one-dimensional modeling of the cell, the excess minority carrier density, the photovoltage, and the capacitance are calculated. The motivation of this work are two-fold: to show base doping density and illumination effects on the capacitance of silicon solar cells, and to propose a determination technique for both dark capacitance and base doping density from C-V characteristics.
