Customer ServiceThe equivalent circuit of a solar cell consists of an ideal current generator in parallel with a diode in reverse bias, both of which are connected to a load. These models are invaluable for understanding fundamental device physics, explaining specific phenomena, and aiding in the design of more efficient devices.
The PV cell equivalent-circuit model is an electrical scheme which allows analyzing the electrical performance of the PV module. This model gives the corresponding current–voltage (I-V) and power-voltage (P-V) characteristics for different external changes such as irradiance and temperature (Chaibi et al., 2018).
Furthermore, the SDM performs well with low fluctuations of temperature and the DDM is more appropriate for medium and high variations. The results prove that the performance of the Photovoltaic Cell Equivalent-Circuit Models is influenced by solar irradiance and temperature.
Therefore, the novelty of this work is to assess the effectiveness of a hybrid approach, obtained by switching from the two equivalent-circuit configurations (the single and the double diode model) according to different levels of solar irradiance and temperature, in order to ensure high accuracy in the photovoltaic cell modelling.
An equivalent circuit model presents a theoretical circuit diagram, which captures the electrical characteristics of a device. It is important to note the components illustrated in the model are not physically present in the devices themselves.
In order to evaluate the electrical performance of the PV cell, diverse equivalent-circuit models are simulated with the main objective is to plot the corresponding I-V and P-V characteristics for different values of irradiance and temperature.
