Abstract
Abstract Equivalent circuit model has been proposed to describe the solar cell characteristics and commonly used is single diode model. Sundry methods are currently utilized to determine the values of voltage, current, and power of a photovoltaic cell. A new method is suggested to numerically find these values using the popular methods, Newton Raphson method (NRM); Aitken’s extrapolation algorithm (AEM) and Three-step method (TSM) at various values of a load resistance R. Equation based on equivalent circuit of a solar cell so all determinations is imlemented in a Matlab in ambient temperature. The obtained results of this new method are given and contrasted with NRM.
