Investigation the Effect of Series Resistance on the Electrical Parameters of Solar Cell using Multisim Software

Abstract

In this paper, a theoretical investigation to the effect of the series resistance ( ) on the solar cell output parameters, such as efficiency (η), open-circuit voltage ( ) , output maximum power ( ) , fill factor (FF) and short circuit current( ) was performed. Multisim software was used to achieve the investigation. It is reproduced by using the current-voltage (I-V) characteristics in accordance with double-diode modeling of the solar cell. The results showed that there is a change in the characteristic curve form due to the variation of series resistance values between (0.01- 0.5) Ohm. Moreover, it was found that the fill factor, short circuit current, and open circuit voltage decreased linearly when the value of the series resistance increased. Consequently, the conversion efficiency of the solar cell declined. In other words, the series resistance has a significant effect on the performance of the solar cell.
