Embodiment Construction
[0032] Below, according to the accompanying drawings, preferred embodiments of the present invention are given and described in detail, so that the functions and features of the present invention can be better understood.
[0033] Embodiments of the present invention include a photovoltaic cell equivalent modeling method, the model used in the method is as figure 1 shown. In this model, I sh Is the photogenerated current, and its value is proportional to the area of the photovoltaic cell and the intensity of the incident light; I D is the current flowing through the equivalent diode; I is the load current output by the photovoltaic cell; U D Is the terminal voltage of the equivalent diode. Under the condition of no light, the basic behavior of the photovoltaic cell is similar to that of an ordinary diode; U is the voltage at both ends of the load; R L is the load resistance of the battery; R S is the equivalent series resistance; R sh is the equivalent parallel resistan...
