An exact analytical method for calculating the parameters of a real solar cell using special trans function theory (STFT)

Abstract

An exact analytical method using special trans function theory (STFT) is presented to calculate the parameters of a real solar cell. Calculated values are compared with other methods. Various characteristic curves are also drawn using the analytical expressions to validate this approach. The effect of the parasitic resistances in the fill factor is studied in detail. Relative percentage accuracy of STFT method is also calculated to show the significance of the method over other methods.
