Abstract

Abstract: The study to the dynamic parameters of the photovoltaic cell is of crucial importance for the design of the corresponding afterward stage controller in the photovoltaic power generation system. Beginning with the analysis to physical mechanism of the photovoltaic cell, more accurate equivalent formulation of the junction voltage and bias voltage of the photovoltaic cells /module/array was deduced, and the explicit formulation between the bias voltage and output voltage was received by using the Lambert W function based on equivalent series resistance and the saturation current. The formulation was adopted which combined the engineering mathematics model and intrinsic carrier concentration to deduce the precise relation between the equivalent capacitance and the temperature. The simulated analysis was made to the impact of the equivalent junction capacitance respectively under different serial/parallel numbers and different temperatures. The simulated result is in accordance with the experimental result of parts of literatures, which verifies the validity of the theory.
