Effect of the Dynamic Resistance on the Maximum Output Power in Dynamic Modelling of Photovoltaic Solar Cells

摘要

style="font-family:Verdana;">Several studies on PV solar cells are found in style="font-family:Verdana;"> style="font-family:Verdana;"> style="font-family:Verdana;">the style="font-family:Verdana;"> style="font-family:Verdana;"> style="font-family:Verdana;">literature which use static models. Those models are mainly one-diode, two-diode or three-diode models. In the dynamic modelling style="font-family:Verdana;"> style="font-family:Verdana;"> style="font-family:Verdana;">, style="font-family:;" "=""> style="font-family:Verdana;"> a variable parallel capacitance is incorporated. Unlike the previous studies which do not clearly establish a relationship between the capacitance and the voltage, in the present paper, the link between the capacitance and the voltage is investigated and established. In dynamic modelling investigated in this paper, the dynamic resistance is introduced in the modelling of the solar cell. It is introduced in the current-voltage characteristic. The value of the dynamic resistance is evaluated at the maximum po style="font-family:Verdana;">wer point and its effect on the maximum power is investigated. The study style="font-family:Verdana;">shows for the first time, that the dynamic resistance must be introduced in style="font-family:Verdana;">the current-voltage characteristic, because it has an influence on the PV cell style="font-family:Verdana;">output style="font-family:Verdana;"> style="font-family:Verdana;"> style="font-family:Verdana;">.
