Abstract- A new technique to evaluate the five illuminated solar
cell parameters with a single diode lumped circuit model. These
parameters are usually the saturation current (Is), the series
resistance (Rs), the ideality factor (n), the shunt conductance
(Gsh) and the photocurrent (Iph).
The method includes the presentation of the standard I=f (V)
function as V=f (I) and the determination of the factors C0, C1,
C2 of this function that provide the calculation of the illuminated
solar cell parameters. Parameter values were extracted using the
present method from experimental I–V characteristics of a
commercial solar cell and a module.
