This paper presents a new technique for the evaluation of the parameters of illuminated solar cell with a single diode lumped circuit model and considering the series and shunt resistances. This method includes the presentation of the standard I= f( V) function as V= f( I) and the determination of the factors C 0, C 1, C 2 of this function that provide the calculation of the illuminated solar cell parameters. These parameters are usually the saturation current ( I s), the series resistance ( R s), the ideality factor ( n), the shunt conductance ( G sh=1/ R sh) and the photocurrent ( I ph). Parameter values were extracted using the present method from experimental I– V characteristics of commercial solar cells and modules. The method proposed below appears to be accurate even in the presence of noise and/or random errors during measurement and it needs no a prior knowledge of the parameters compared to other methods.
