Starting from an electrical dissipative illuminated one-diode solar cell with a given model data at room temperature (Isc, Voc, Rs0, Rsh0, Imax); we present under physical considerations a specific mathematical method (using the Lambert function) for unique determination of the intrinsic electrical parameters (n, Is, Iph, Rs, Rsh). This work proves that for a given arbitrary fixed shunt resistance Rsh, the saturation current IS and the ideality factor n are uniquely determined as a function of the photocurrent Iph, and the series resistance Rs. The correspondence under the cited physical considerations: Rs does not exceed ]0, 20[Ω and n is between ]0, 3[ and Iph and Is are arbitrary positive, is biunivocal. This study concludes that for both considered solar cells, the five intrinsic electrical parameters that were determined numerically are unique.
