An Improved Model of Photovolatic Cell Using Lambert W Function

Abstract:

In this paper, an improved model of photovoltaic cell is proposed. By using Lambert W function, the improved model of solar cell is deduced. Meanwhile, the current-voltage and power-voltage curves of photovoltaic cell are calculated and simulated in Matlab/Simulink environment. Compared to the popular model and experimental data, the proposed method shows excellent agreement between the current-voltage points. It is found that the proposed modeling method has less error at the maximum power point state.
