ANALYTICAL EXPRESSION FOR THE CURRENT-VOLTAGE CHARACTERISTIC OF PV CELLS BASED ON LAMBERT W-FUNCTION FOR ITS FORWARD AND REVERSE BRANCHES

Annotation. Two-diode model of PV cell is proposed, which makes it possible to present in a unified analytical form the full current-voltage characteristic considering both forward and reverse branches based on the Lambert W-function. The model allows a fairly detailed study the effect of avalanche breakdown mechanism in the p–n junction on the reverse branch of the I–V characteristic. Good fitting has been show between the experimental and modeled I-V curves for silicon PV cells. From a practical point of view, a unified analytical form of the full current-voltage characteristic with Lambert W-functions is allows to analyze behavior of the series connection of PV cells and modules under uneven illumination in running solar power plants.
Keywords: solar energy, an analytical two-diode Shockley model of a PV cell, a full current-voltage characteristic based on the Lambert W-function, avalanche electrical breakdown, operational parameters and characteristics of PV cell.
