In this paper, we present a new method of extracting the model physical parameters of an illuminated solar cell, composed of series and shunt resistance. The method is based on analytical solution of the equation derived from the current-voltage (I-V) characteristics. The equation obtained is expressed in terms of I, V, and the derivative (dI/dV). The model parameters can then be easily determined by numerical fitting. The obtained results show a good agreement with those obtained by the method proposed by Ortiz-Conde et al., and by the five-point method. |
