Effect of Electrical Model, Temperature, and Generation Rate on the Photovoltaic Module Parameters

Abstract

AbstractThis paper proposes a two-diode model to represent the photovoltaic cell. This model requires only three parameters (photocurrent, diffusion, and recombination of the dark current). The analytical resolution of continuity equations in each region of a crystalline solar cell enabled the determination of the expressions of diffusion and recombination of dark currents. New relationships are proposed giving the expressions of these currents as a function of their reference values, which are determined from both the data provided by the manufacturer and the different temperature values. This study indicated how the parameters of the proposed model were determined. Predicted current–voltage curves were compared with the De Soto one-diode model and experimental data from a building integrated photovoltaic facility at the National Institute of Standards and Technology (NIST) for two different cell technologies (single crystalline, polycrystalline). The maximum power calculated by the proposed model was ca...
